Integrated-optic versus micro-optic devices for fiber-optic telecom systems : a comparison

We assess the relative merits and prospects of integrated-optics in comparison with microoptic and fiber-based techniques. Firstly, the market for fiber-optic components for telecommunications is analyzed. Secondly, the technological issues which make integrated optics quite different from integrated electronics will be discussed. Thirdly, a specific comparison between the potential of the competing optical technologies will be made for the polarization-diversity hybrid and the optical wavelength (de)multiplexer, two optical devices used in networks that are based on optical frequency division multiplexing (OFDM

Space-switching using wavelength conversion at 2.5 Gb/s and integrated phased array routing

Space switching of 2.5 Gb/s optical signals by lambda -conversion in a DBR laser and subsequent routing through a phased array wavelength demultiplexer is demonstrated. A novel component is presented that integrates 3 dB couplers and a phased array to form the passive part of a space switc
