The insertion losses of silicon oxynitride (SiON) waveguides have been measured in the 1550 nm wavelength region. The waveguide structure consisted of a 2.0µm SiON waveguide core with a refractive index of 1.50, a 0.5µm SiO2 upper cladding and a 5.

A concave grating etched into a planar waveguide can be used to demultiplex signals from a wavelength division multiplexed telecommunication system. After the effective index of the waveguide is specified, a grating can be designed so that each chann

The temperature-dependent electrical conductances of sets of ultrathin amorphous Pd films prepared by successive deposition in situ at low temperatures have been found to scale over a range of conductances encompassing both the strongly and weakly lo

We demonstrate adiabatic wavelength insensitive 2×2 PLC coupler with less than 0.6 dB variation over 1260- 1630 nm range and better than 0.25 dB PDL. We use it to build process tolerant 2×32 splitter having excellent optical performance.

We report extremely efficient (∼100% internal quantum efficiency) and high‐speed (∼120 ps lifetime) photodetection in a reversed biased InGaAs/InP ridge‐waveguide multiple quantum well p‐i‐n laser structure operating at 1.54 μm. The impu

An integrated optical demultiplexer is an ideal device for the measurement of the effect of strain (or, equivalently, stress) on birefringence. We fabricated optical demultiplexers from silicon oxynitride optical waveguides and measured the strain de

The total internal reflection (TIR) grating is an integrated optical diffraction grating designed to achieve high efficiency for the retrodiffracted order by use of total internal reflection twice within a groove of the grating rather than by use of
