摘要： A nanophotonic Mach-Zehnder interferometer (MZI) (20) device having at least one arm (50) which has an actual length greater than its virtual length (L f ). An arcuate section (52) is provided in at least one arm (50) (thus providing a "meandering arm") to increase the actual length of that arm without increasing its virtual length (L f ) and without compromising the ability of that arm to effect a π phase shift in an optical signal propagating therein. By constructing the MZI device of strongly confined waveguides, which may be either photonic-well or photonic-wire devices, the low bending loss characteristics of such waveguides enable the use of an arcuate section (52) or bend in the waveguide without experiencing undesirable losses in the optical signal. The actual length of the arm and the optical length are equivalent to those for prior art devices and sufficient to introduce the desired phase shift. In contrast to prior art devices, however, the present invention provides those sufficient actual and optical lengths in a significantly reduced length on the chip (i.e., its virtual length) that requires less on-chip real estate and thus provides for denser integration of a plurality of optical devices in an optical component.

摘要： A polarization diversity scheme for managing the polarization dependence of a microring resonator which employs two resonators serially arranged and constructed to separately filter transverse electric (TE) and transverse magnetic (TM) polarization components of a predetermined wavelength in a randomly polarized DWDM optical signal, and to recombine the separately filtered components prior to output from an optical component employing the inventive polarization diversity scheme.

摘要： A surface-emitting optical amplifier (10) having a generally circular waveguide (30) and active region (20). The waveguide (30) and active region (20) match the shape of an optical fiber or other device for generating, transmitting, guiding, propagating, etc., an optical signal. For example, the shape of the waveguide (30) and active region (20) may be circular, elliptical, square, rectangular, or virtually any other required shape. By matching the shape of the waveguide (30) and active region (20) to the shape of the device to which the waveguide connects, coupling loss is reduced and polarization dependent loss is eliminated due to the symmetry of the active region. The reduction of the coupling loss also leads to an increase of the signal to noise ratio since the signal loss from the input coupling is directly reduced.

摘要： An optical resonator having a non-continuous waveguide having first and second confrontingly opposite end faces between which is defined a region and having a continuous optical path defined through the waveguide. The optical resonator can be tuned to a particular resonant wavelength by providing a phase shifter in the region between the first and second end faces and positioning the phase shifter so as to introduce a phase shift in an optical signal propagating through the waveguide and along the optical path. A method for effecting such a phase shift.

摘要： A semiconductor dry etching process that provides deep, smooth (RMS of less than approximately 5 mm), and vertical etching of InP-based materials with ICP RIE using a chlorinated plasma with the addition of hydrogen gas. Inert gases such as nitrogen, argon, or both may also be included. To produce relatively high anisotropy with exceptionally smooth surfaces, the amount of hydrogen gas added preferably exceeds the volumetric measure of chlorinated gas in standard cubic centimeter per minute (sccm); at a radio of greater than 1:1. The present invention provides an improved dry etching process for InP-based semiconductor materials that yields deep, vertical etch profiles with improved surface smoothness (i.e., morpology) and high manufacturing etch rates.

摘要： An optical switch having an input waveguide and two output waveguides separated by and disposed around a trench. The input waveguide and a first output waveguide have respective optical paths defined by their respective cores; those optical paths (and cores) being aligned or coaxial with each other. Those waveguides are also separated by a trench having a medium provided therein that has a refractive index different from that of the waveguides. The input waveguide and first output waveguide are separated by a distance insufficient to affect the transmission characteristics of an optical signal propagating from the input waveguide to the first output waveguide, even though the optical signal experiences different refractive indices as it propagates from the input waveguide to the first output waveguide. The input waveguide and a second output waveguide are arranged generally on the same side of the trench such that an optical signal passing from the input waveguide to the second output waveguide does not completely traverse the trench. Thus, even though an optical signal passing from the input waveguide to either of the first or second output waveguide encounters different refractive indices, the distance over which the optical signal must travel between the waveguides is small enough so as to not affect the optical transmission characteristics of that signal.
