摘要： Tunable laser devices and methods of manufacturing such devices are disclosed. In particular, the laser device may include a layer of photonic crystal having a lattice of air-holes with defects that form an optical waveguide. The waveguide has a cross-sectional area whose dimensions are in sub-wavelength ranges, wherein the cross-sectional area is perpendicular to the propagation direction of light in the waveguide. The waveguide receives pump light and outputs Stokes light through Raman scattering. The laser device may include a photonic crystal made from silicon having air-holes with defects forming a pair of optically coupled cavities. The geometries of the cavities can be substantially identical to each other. The cavities are defined to cause a frequency-splitting difference between a frequency of pump light and a frequency of Stokes light to correspond to an optical phonon frequency in silicon through Raman scattering.

摘要： High-speed hitless switches (10, 12) for directing optical beams are provided. These switches may use semiconductor-based materials whose refraction and absorption characteristics are modified by applying a voltage. The induced changes in these characteristics allow an optical signal to be directed from one branch to another without the loss of any signal data. These switching devices (10, 12) may be cascaded in a Mach-Zehnder configuration with each switch residing in the coupling area of the Mach-Zehnder configuration. The use of a multi-section switching device may also be performed so that certain optical losses can be reduced and better tuning can be achieved. A capacitive phase shifter (19) in the pi shift region of a Mach-Zehnder configuration may also be used to remove certain frequency dependencies.
