Fabrication of SU-8 slab- and ridge-waveguides with holographic grating for DFB laser, effectively utilizing nanoimprint technology (NIL), is presented. Rhodamine-6G-doped SU-8 slab- and ridge-waveguides were embedded in grooves defined by NIL in UV

We fabricated quantum well (QW) microtubes by rolling up thin films containing QWs and measured their photoluminescence (PL) properties. Before fabricating microtubes, no PL signal is observed in the QW at all, because their band configuration is ind

We have developed a system of compositing three-dimensional (3D) video images based on the depth information of the objects. The system consists of the Axi-Vision Camera that can measure object distance in real time and an arithmetic image processor

Chaotic signals with a flat power spectrum over 20 GHz have been generated using two commercially available semiconductor lasers coupled in a unidirectional master-slave scheme. The master laser has an external optical feedback that induces optical c

InAs QDs on GaAs substrates were grown by molecular beam epitaxy (MBE). The dot density and properties were studied by atomic force microscopy (AFM). The low temperature photoluminescence (PL) characteristics of InAs QDs with different cap layers are

We experimentally investigate the synchronous response of a semiconductor laser to the injection of a periodic or chaotic oscillating optical signal that is generated by a similar semiconductor laser with optical feedback. We show that there are two

We show that modulated near-infrared radiation can generate terahertz plasma oscillations in the channel of a high-electron mobility transistor. This effect is associated with a temporarily periodic injection of the electrons photoexcited by modulate

We study the performance of a lateral p–n junction quantum-well edge-emitting laser-transistor with an extra gate contact. The incorporation of the gate contact provides an opportunity to control the threshold current and output optical power by th
