Title 
Photonic integrated circuits for optical communications and microwave photonics
Abstract 
Broadband and low attenuation capabilities of optical fibers have led to anever-increasing interest in their use for communication and microwave systems. In order to fully exploit the bandwidth offered by optical fibers, optical signal processing using photonic integrated circuits (PICs) has been proposed to achieve higher capacity, lower cost, size and power consumption. In this work, weinvestigate feasible PICs approaches for high spectral efficiency optical communications and wide-band microwave photonics. For high spectral efficiency optical systems, we firstly report the characterisation of a silicon orthogonal frequency division multiplexing (OFDM) transmitter including four modulators and a Fourier transform, and then demonstrate Nyquist pulse generation using a finite impulse response filter chip. Lastly, we illustrate a ring resonator assisted-tapped delay line circuit for Nyquist wavelength 

division multiplexing (WDM) receiver. For wide-band microwave subsystems, an integrated tunable delay line that overcomes the delay-dependent loss is verified, and an integrated microwave photonic method of a binary-phase-coded millimeter-wave signal generation is demonstrated.
