Soa amplifier datasheet

It is a very compact unit optimized for single-shot to CW performance with pulse width lengths down to 1 nanosecond. This SOA pulsed driver delivers precision pulses which are generated internally by an on-board pulse generator, or on demand from an external TTL signal. Semiconductor Optical Amplifiers driven in nanosecond pulse regime can be compared with AOMs, EOMs or direct laser diode modulators see comparative table. It is the only solution meeting all the constraints for a reliable, stable and efficient fibered modulation.

C-Band Optical Amplifiers (BOAs and SOAs), 1550 nm


Thorlabs has integrated our fiber-coupled optical amplifiers into easy-to-use benchtop units. The drive current can be modulated at up to kHz using an input signal from 0 - 5 V corresponding to zero transmission and maximum gain, respectively via a BNC connector located on the rear panel of the unit. An internal microcontroller ensures that the amplifier is not overdriven from the modulation voltage.

The USB interface allows these amplifiers to be controlled remotely via a PC see the manual for a list of commands for running the unit from a command line interface. BOA vs. SOA A booster optical amplifier BOA is a polarization sensitive device that only amplifies light with a specific polarization. Our BOAs are pigtailed with PM fiber and will amplify light aligned to the slow axis of the input fiber connector.

Our benchtop BOAs are available with center wavelengths at , , , , and nm. For amplication at nm, we also offer a semiconductor optical amplifier SOA that provides polarization-insensitive amplification at a lower maximum gain than the BOA counterpart. For more information on amplifiers, see the Optical Amplifiers tab above. The optical feedback from the end faces establishes a cavity in which lasing can occur.

The AR coatings limit the optical feedback into the chip so that lasing does not occur. When used to amplify a modulated signal, the linear regime is typically used to eliminate pattern-dependent distortion, multi-channel cross-talk and transient response issues common to EDFAs.

The non-linear regime is used to take advantage of the highly non-linear attributes of the semiconductor gain medium cross-gain modulation, cross phase modulation to perform wavelength conversion, optical 3R regeneration, header recognition, and other high-speed optical signal processing functions. For a CW input signal, the amount of power that can be produced by the amplifier is determined by the saturation output power P sat parameter.

P sat is defined as the output power at which the small-signal gain has been compressed by 3 dB. The maximum amount of CW power that can be extracted is approximately 3 dB higher than the saturation power.

Is it right? Is it normal? Hi, Thanks a lot for reading this message. We bought this SOA recently. I wonder if is can be used bidirectionally. Can I put the light into the output port and get the amplified light at the input port?

According to the datasheet, there are no isolators inside the SOA. I should be most grateful if you would reply to me. All my best, Luan. Hello Luan, thank you for contacting Thorlabs. The SOA is built with a symmetric structure so they can be used bidirectionally.

If it is operated backwards, the gain will stay the same, but saturation power and noise figure will be different if coupling efficiency of input and output fibers are different, which can be true in practice. Such as S9FCS polarization independent. Gong-Ru Lin. Thank you for contacting Thorlabs. This is usually a preferred option since the polarization in the single mode fiber is sensitive to stresses, vibrations, and changes in temperature.

In this case, the fiber itself is accessible when using the CLD for any manipulation for polarization using the fiber polarization controllers. What will happen when it is used for a transform limited pulse nm.

The width of the pulse is about 50fs. Will the pulse get wider or get chirped? Can I specify a center wavelength at the short wavelength end nm given in the specs?

Thanks, Trevor. I have found that feeding the OA output into the interferometer gives interference fringes, even if no input light source is used i. What's more, if we connect a loose optical fibre to the OA input - still with no input light source - the signal is amplified by a factor 10, and the coherence length increases by a factor 10 approx. We are wondering if you know what is causing this effect presumably the noise amplified has a temporal coherence determined by the amplifier medium's spontaneous decays , particulaly what is happening when we connect a loose fibre.

Many thanks, Sid Wright. Hi, I am looking for an optical amplifier for our silicon photonics setup. We work with TE polarization type waveguides. I am trying to decide between polarization maintaining or polarization insensitive optical amplifiers. Are there selective to one polarization? Do they change the polarization of the output light?

The advantage of the BOA series is the higher gain achievable. The selection of this will depend on your exact application and how you plan on using them. I will contact you directly to discuss about this further. You list a possible center wavelength at I am trying to figure out if this product S7FS can amplify , and what would be the saturation output power.

Could you tell me? The saturation output power will be lower at nm; we estimate around 11dBm. The nm number is the center of the ASE curve but the gain curve is typically shifted some to longer wavelengths.

This new optical amplifier is able to function seamlessly in this fluid spectrum DWDM world.

SOA 1013: 1550nm C-band Semiconductor Optical Amplifier

SOA Calculations. I'm starting a new thread to discuss the calculations of SOAs and protection circuits, in regular pushpull class AB designs. I'm making some calculations but I'm not certain I'm doing this right, so perhaps someone will be able to bring some insights. First I'd like to make sure I am properly collecting the SOA data from datasheets for use in plotting this curve digitally for comparisons with load lines later. I think it might be a good tool to use excel to store that data. Such sheets could be posted here for sharing.

The Optilab SOABP is a semiconductor optical amplifier with high fiber-to-fiber gain, designed to be used in general applications to increase optical.

Antireflective processing is applied on both facets of a semiconductor laser to eliminate the resonator structure. When light enters from outside the semiconductor, the light is amplified by stimulated emission. SOA is used for amplifying an optical signal.

Optical amplifier , with the introduction in the s, conquered the regenerator technology and opened doors to the WDM technology. It is mainly used to amplify an optical signal directly, without the need to first convert it to an electrical signal. This article will make a clearer introduction to SOA amplifier, and analyze its advantages and disadvantages. SOA optical amplifiers use the semiconductor as the gain medium, which is designed to be used in general applications to increase optical launch power to compensate for the loss of other optical devices.
