An output power of 5 mW has been demonstrated at 290 GHz by tripling a primary signal in the W band. The nonlinear devices are high performance InP-based heterostructure barrier varactors mounted in mechanically tuned waveguide harmonic multiplier. The flange-to-flange maximum efficiency was 5%...

Growth of strained Ga_1-xIn_xP layers on GaP (001) by gas source molecular beam epitaxy: similarities and differences with the growth of strained arsenides

X. Wallart, D. Deresmes, F. Mollot

Using reflection high energy electron diffraction and atomic force microscopy, the growth of Ga1−xInxP alloys on GaP (0 0 1) with x varying from 0.2 to 1 (InP) is investigated and compared to that of arsenides on GaAs (0 0 1) or InP (0 0 1). At 520°C, the evolution of the critical thickness for 3D...
