A monolithic integrated photonic microwave filter

InP-Based Monolithic Photonic Integrated Devices

We present our recent work on monolithically integrated devices comprising a variety of functional elements such as high speed optical transmitters and receivers, electro-absorption modulators integrated with tunable dispersion compensators and fast-tunable wavelength converters. key words: photonic integration, wavelength converter, high speed modulator and receiver, advanced modulation format

Passband switchable microwave photonic multiband filter

A reconfigurable microwave photonic (MWP) multiband filter with selectable and switchable passbands is proposed and experimentally demonstrated, with a maximum of 12 simultaneous passbands evenly distributed from 0 to 10 GHz. The scheme is based on the generation of tunable optical comb lines using a two-stage Lyot loop filter, such that various filter tap spacings and spectral combinations are...

Photonic crystal filter integrated with photodiodes

We demonstrate the monolithic integration of photonic crystal waveguides, a photonic crystal demultiplexer, a conventional waveguide and photodiodes in InGaAsP-based material. The photonic crystal demultiplexer consists of hexagonally arranged air holes. The inputted light at the wavelengths of 1530nm and 1550nm can be separated by the demultiplexing system.

Monolithic Microwave Integrated Circuit (MMIC) Technology for Space Communications Applications

Expert system issues related to monolithic microwave integrated circuit design

Artificial Intelligence (AI) techniques are applied to develop a framework for the design and layout of MMIC circuits. This framework addresses key aspects of the design process, from circuit specification and initial design decisions through to final layout and preparation of the circuit for fabrication. A number of knowledge-based systems are incorporated into the framework to assist in speci...
