We demonstrate a comb-based tunable transmitter with potential to be integrated on a single InP photonic chip. A Nyquist-shaped polarization-multiplexed 16QAM signal with 7.1 bit/s/Hz spectral efficiency is generated and transmitted over 300-km of SM

We have investigated the suitability of InP-based push-pull modulators to generate flat optical comb spectra. The residual amplitude modulation that was a consequence of driving the modulator well above its design voltage (up to 4V[pi]) is demonstrat

We report an InP coherent receiver chip with the highest reported responsivity (0.15A/W) together with excellent RF bandwidth (32GHz) and 4x4 MMI width fabrication control (< ±60nm 90% population) providing a highly manufacturable Rx for CFP2 module

We report the development of a polarization insensitive all fiber 2/spl times/2 acoustooptic switch based on twisting the waist of a null taper coupler. The polarization insensitivity is better than 0.2 dB, the device requires a drive power of

We have demonstrated a broadband, polarization-independent all-fiber switch. It is based on twisting the waist of a null taper coupler. The polarization sensitivity is reduced from 17 dB to 0.2 dB. The device has a low drive power requirement, low in

It is shown that the controlled multi-tapering of singlemode optical fibres can be considered as another degree of freedom in tailoring the spectral characteristics of dynamic acousto-optic filters. This results in optical filters with complex spectr

An all-fiber acoustooptic switch has been constructed from a 3/spl times/3 null fused coupler. The maximum drive power required is 4 mW, the switching time is 100 /spl mu/s and the insertion loss is less than 0.5 dB and has a cross talk of 20 dB. The
