InP and silica photonic integrated circuits for high spectral efficiency fiber-optic communications
14 June 2009
This talk will focus on silica PICs and InP PICs. Silica PICs are well suited for in-line components, which must be low loss and can have slow dynamics. InP PICs are well suited for transmitters and receivers, which must provide light generation/amplification, high-speed modulation, and high-speed reception. For silica PICs we will discuss optical equalizers, which can correct for the intersymbol interference commonly encountered in high spectral efficiency systems; interleavers for ultra-narrow channel spacings; demodulators for differential quadrature phase-shift keying (DQPSK); and modulators built using a combination of silica and LiNbO3.
