We report a method of optical excitation of nanomechanical cantilever-type oscillators. The periodic driving signal with a controlled modulation amplitude was provided by a 415 nm diode laser, wherein the laser spot was located at some distance away from the clamped end of the cantilever. The measured resonant response of the cantilever was obtained at distances in excess of 160 μm with varying oscillator dimensions. The effectiveness of the driving mode is studied for different combinations of materials, namely Si–SiO2 and Si3N4–SiO2. These observations were considered within the theoretical framework of the mechanism of heat transfer. We show that measurable amplitudes of vibrations can be obtained at temperature changes much less than 1°.

    Replacing a portion of the upper III-nitride cladding with indium-tin-oxide (ITO) has several potential advantages for GaN-based laser diodes (LDs). For green LDs, use of ITO in the waveguide structure reduces the epitaxial p-cladding thickness and growth time, which in turn may reduce thermal...

    We examine the behavior of two microlensed diode lasers at 413 and 661 nm placed in both free-running and extended cavity geometries. The 25 mW free-running 413 nm diode shows current tuning over 40 GHz and the 50 mW, 661 nm diode shows tuning of 55 GHz. In extended cavity the 413 nm diode...

    Anomalous transition to the regime of dynamic chaos in a multimode quantum-well heterolaser (λ = 635 nm) is possible as a result of an injection-current-induced change in the gain. A stable multimode regime (featuring more than ten longitudinal modes) is established near the lasing threshold...
