Nitride based violet laser diodes grown on GaN substrates have been investigated. A grooved substrate, having a striped pattern with a pitch of 400 μm, has been prepared and epitaxial growth has been performed. No cracks have been observed in the ep

The use of commercial laser diodes as near field, nano-scale position sensors for feedback control systems was experimentally investigated. A static experimental setup was constructed to measure and characterize the laser diode feedback mechanism. Ex

Ohmic contact formation on a p-GaN layer with a specific contact resistance of ρc=5×10-4 Ωcm2 has been achieved using a Pd/Mo electrode without the use of an alloying process. ρc was reduced to 2×10-4 Ωcm2 by annealing in vacuum at 500°C. The

AlGaInN violet laser diodes grown on GaN substrates have been studied. Waveguide simulations have been performed and perpendicular radiation angles have been investigated. A peculiar layer structure has been proposed to reduce the perpendicular radia
