We present novel designs and demonstrate a fabrication platform for electrically driven lasers based on high quality-factor photonic crystal cavities realized in mid-infrared quantum cascade laser material. The structures are based on deep-etched ridges with their sides perforated with photonic crystal lattice, using focused ion beam milling. In this way, a(More)
— There is a lack of timely access to necessary healthcare in remote areas, especially in India. This paper addresses the availability of quality healthcare, by introducing wireless technology to monitor patients, in remote areas. A reliable system to continuously monitor the patients in the remote areas has been developed, this software suite consists of(More)
We have investigated both theoretically and experimentally the spectral behavior and the transmission and reflection performance of a photonic-crystal (PhC) mode converter upon an InP substrate. This taper exhibits 70% transmission efficiency on an 80-nm bandwidth when it couples a ridge access guide to a strongly confined single-missing-row PhC guide. Such(More)
