    摘要: A sensing system can include one or more particles having one or more plasmon resonances. The particles can be positioned adjacent to the active region of a sensor to enhance the sensitivity of the sensor to electromagnetic radiation having frequencies corresponding to the plasmon resonances. An array of sensors such as used for color imaging can employ different types of particles adjacent to different sensors, so that different sensors sense different colors. During fabrication of such sensors, the particles can be applied mechanically or using a process such as inkjet printing.

    摘要: A system can include a transmitter that produces an optical signal having a plurality of carrier frequencies and a receiver separated from the transmitter by free space through which the optical signal propagates. The receiver includes an array of detectors of multiple types, with the types being capable of detecting light respectively having the carrier frequencies. A location of an incident area where the optical signal is incident on the detector array generally depends on a misalignment of the receiver relative to the transmitter, but the detectors in the detector array are arranged so that at least one detector of each of the types detects light from the optical signal regardless of where the incident area is on the detector array.

    摘要: An optical connector includes a first optical fiber and a second optical fiber. A first planar lens is positioned to operate on light exiting the first optical fiber to create a predetermined change in a wave front of the light. A second planar lens is positioned to accept the light from the first planar lens, the second planar lens focusing the light onto the second optical fiber. The first planar lens and second planar lens each include a regularly spaced array of posts with periodically varying diameters.

    摘要: A vertical cavity surface emitting laser (VCSEL) system and method of fabrication are included. The VCSEL system includes a first portion comprising a first mirror and a gain region to amplify an optical signal in response to a data signal, the first portion being fabricated on a first wafer. The system also includes a second portion comprising a second mirror that is partially-reflective to couple the optical signal to an optical fiber. The second portion can be fabricated on a second wafer. The system further includes a supporting structure to couple the first and second portions such that the first and second mirrors are arranged as a laser cavity having a predetermined length to resonate the optical signal.

    摘要: A vertical cavity surface emitting laser (VCSEL) system and method of fabrication are included. The VCSEL system includes a gain region to amplify an optical signal in response to a data signal and a first mirror arranged as a partially-reflective high-contrast grating (HCG) mirror at an optical output of the VCSEL system. The VCSEL system also includes a second mirror. The first and second mirrors can be arranged as a laser cavity to resonate the optical signal. The VCSEL system further includes a doped semiconductor region to generate a current through the first mirror in response to a voltage signal to substantially alter the reflectivity of the first mirror to provide Q-switching capability of the VCSEL system.
