Abstract: An infrared photo-detector with multiple discrete regions of a first absorber material. These regions may have geometric shapes with sloped sidewalls. The detector also may include a second absorber region comprising a second absorber material that absorbs light of a shorter wavelength than the light absorbed by the multiple discrete absorber regions of the first absorber material. The geometric shapes may extend only through the first absorber material. Alternatively, the geometric shapes may extend partially into the second absorber region. The detector has a metal reflector coupled to the multiple discrete absorber regions. The detector also has a substrate containing the discrete absorber regions and the second absorber region. The substrate can further include geometric shaped features etched into the substrate, with those features formed on the side of the substrate opposite the side containing the discrete absorber regions and the second absorber region.

Abstract: An photonic RF circulator is described that provides greater than 40 db of isolation between a Received RF signal and a Transmitted RF signal in a simultaneous transmit and receive device. The photonic RF circulator uses light modulated in an optical waveguide grating where the Received RF signal co-propagates with the light and the Transmitted RF signal counter-propagates with the light. Variations described within provide for broadening the bandwidth of the T/R isolation and rejection of various noise sources.

Abstract: Systems and methods for a multi-band position sensor and a multi-band optical detector are disclosed. This system comprises a dual-axis, lateral-effect position sensor for locating spots of light that has energy in two wavelength bands. This sensor senses the time-varying intensities of the light in each of the two wavelength bands. This sensor also provides the location of the spot of light on the light-detecting plane of the sensor. Examples are provided for light of two mid-wave infrared (MWIR) wavelength bands or of a short-wave infrared (SWIR) and a MWIR band. This sensor approach, could be applied to detect light of other wavelength bands, such as a combination of a MWIR and a long-wave infrared (LWIR) band. This concept is extended to an array of detectors for multi-band optical detection and multi-source location and tracking. Monolithic chip level fabrication of the multi-band detectors is also discussed.
