Abstract
Slow-light effects in photonic crystal (PC) waveguides can enhance
light–mater interaction near the photonic band edge, which can be
used to design a short cavity length semiconductor optical amplifier (SOA).
In this paper, a novel SOA based on slow-light effects in PC waveguides
(PCSOA) is presented. To realize the amplification of the optical signal
with polarization independence, a PCSOA is designed with a compensated
structure. The cascaded structure leads to a balanced amplification to the
TE and TM polarized light.
