The characteristics of the longitudinal mode hops of 1060-nm high-power DBR lasers are studied. We demonstrate a return-to-zero technique for eliminating large mode hops and wavelength hysteresis caused by the photon-induced gain saturation effect.

We describe the design and fabrication of a lambda/4 phase-shifted laterally-coupled distributed-feedback laser. The third-order grating for distributed-feedback is fabricated without regrowth using stepper lithography, a process that is amenable to high-yield, low-cost manufacturing.

Linear and nonlinear nanoplasmonic effects - such as resonant absorption, second-harmonic generation and extraordinary optical transmission- are modulated in metallic nanostructures when the local dielectric environment is altered by the ultrafast metal-insulator transition in vanadium dioxide.

The channel of high electron mobility transistor can act as a resonator for the plasma waves propagating in 2D electron gas. The plasma frequency increases with reduction of the channel length and can reach the Terahertz range for nanometre size transistors. This work presents an overview of the experimental results on THz detection and emission by nanometre size transistors and multi-grating structures with nanometre size gates.
