Fabry perot amplifier

Semiconductor Optical Amplifiers. It is sensitive to temperature and input optical frequency. Non-resonant traveling-wave amplifiers . Solid State Amplifier Gain VS Power . The most popular methods to study optical amplifiers are based on Fabry – Pérot and rate equation approaches.

Optical bistabilities have been considered to be useful for sensor applications.

In this paper, the bistable characteristics in FPSOAs are investigated theoretically.

High gain but non-uniform gain spectrum. Broadband but very low facet reflectivities are needed. The amplification function is achieved by externally pumping the energy levels of the material. In order to get only the amplification function, it is necessary to protect the device against self-oscillations generating the laser . Depending on the initial detuning of the optical signal beam, both normal (counterclockwise) and reverse . A Theoretical and Experimental Investigation of.

The influence of the spontaneous emission coefficient, . Gain ripple with frequency is evident. Decreasing reflectivity of FP reduces the gain ripple and the gain. Fabry - Perot amplifier exhibits strong Fabry-Perot features. In the limit of R= the response of the FPA is that of the TWA. Good agreement is found with experimental , with the simulation accurately reproducing all the major characteristics of the amplifier.

To our knowledge, this is the first . Current injection allows us to tune the resonant wavelength as well as provide the gain required for all-pass reflection, which leads to group delay tunability with relatively . Important parameters for optical amplifiers include: i. FPLAs) are interesting devices not only for signal amplifica- tion but also for optical bistability and switching because of their large nonlinearity. A 16-dB recovery of the signal-to-noise ratio . Abstract—We simulate the injection-locking performance of a. Our are compared to those of other authors, . In the single passband microwave photonic filter, .
