An integrable all-optical clocked D type flip-flop is demonstrated exploiting SOA-based transparent all-optical SR latch. Nonlinear effects of four wave mixing and cross gain modulation are used for optical logic gate operations.
This paper investigates the first demonstration of linearization of semiconductor optical amplifier (SOA) using feed forward linearization. For improving the linearity and suppressing the four wave mixing (FWM) of SOA the amplifier uses the feed forward technique. This technique should be applicable to any microwave or even millimetre frequency band and any externally modulated laser. Link performance...
We describe the design and development of a novel tunable fiber laser and its application to polarization-mode dispersion measurements of optical fibers using broad-band orthogonal-pump four-wave mixing in a semiconductor optical amplifier.
