The growth, by MOVPE, and characterisation of multilayer reflective stacks have been examined. Reflectivities of 55%–60% into air have been obtained for relatively thin (7 period) structures using both GaInAsP/InP and GaAlInAs/InP material combinat

For the first time, a laser and high-speed modulator are integrated using a common shallow etched ridge waveguide. Ion implantation lateral to the modulator ridge provides electrical isolation suitable for 10 Gb/s long reach, 55 /spl deg/C operation.

A surface ridge DBR laser has been fabricated using conventional InP processing techniques, with the Bragg gratings defined by e-beam lithography. For a phase grating comb spacing of 6.8 nm, a nine grating device is predicted to yield complete covera

Actively aligned fibre termination can be a significant cost contribution to the manufacture of optoelectronic components. Micro-machined piece-parts can allow a self-aligned construction to be used, with consequent savings. This paper describes the
