Abstract
3-dB couplers integrated on InGaAlAs/InP grown by Molecular Beam Epitaxy (MBE) have been studied designed and fabricated. The device structure is based on the modal interference principle modelling has been performed by beam propagation and effective index methods and on this basis devices were designed covering a range of geometrical parameters. Devices have been fabricated on single and double heterostructures by wet chemical etching and characterized over the 1. 47-1. 53 im range by a tunable color center laser. Balanced coupling has been observed in several devices with a best one of output balanced within 0. 1 dB over 15 nm.
