Further development in optical fiber communications at 1.3 and 1.5 /spl mu/m not only requires the improvement of components, but also hinges on the capability to fabricate optoelectronic circuits on a mass scale. Hybrid and monolithic integration of

In this paper we describe the monolithic integration, in the InP/InGaAsP material system, of a polarization diversity optical heterodyne receiver. The study concerns different components which are part of the device: polarization splitters, adjustabl

We report what is to our knowledge the first optimization of a spot size transformer by use of a periodically segmented waveguide for photonic integrated circuits based on InP. It is shown that a nonlinear variation of the segmentation ratio along th

We report here on an InP-switch matrix based on laser-amplifier gates with gain- and polarization-insensitive (as low as 1 dB) operation. A novel integration scheme is demonstrated that provides over 10 dB net chip gain for both input polarizations.

A spot-size transformer structure is proposed for InP/InGaAsP double-heterostructure (DH) rib waveguide. Vertical expansion of a factor of 7 is achieved with 3 dB internal loss. Coupling from standard cleaved fibre (11 /spl mu/m diameter mode) to a D
