A virtual distributed optical crossbar local area network configuration where the central switch or network controller has been eliminated. A virtual distributed optical crossbar allows a network to be fully scalable as the number of users increases. The virtual distributed optical crossbar is fully non-blocking and is reconfigurable. In addition the virtual distributed optical crossbar has zero latency across the network, employs vertical cavity surface emitting laser technology and smart pixel technology in conjunction with a resonant cavity enhanced (RCE) waveguide grating coupler (WGC). Optical signals are transmitted through fiber optic and/or waveguide or freespace interconnects implementing the switching functions. The waveguide technology provides the enabling mechanism to achieve a zero latency, fully non-blocking, performance. Address decoding functions between processors is divided, leaving only the true distance interconnect implemented by optical means.

A high-power coherent array of Vertical Cavity Surface Emitter Lasers is described in which a plurality of Vertical Cavity Surface Emitting Lasers (VCSELs) are provided along with a structure which optically couples each of the VCSELs the plurality of VCSELs to one another by a predetermined amount to cause a coherent mode locking condition to occur. The coupling structure can be a beam cube, a plurality of smaller bean cubes, or a waveguide/grating system, for example. A reference source, or controlled coupling among the VCSELs, is used to phase lock the VCSELs to one another.

A wavelength division multiplexing (WDM) module for transmitting and/or receiving multiple signals simultaneously includes an array of vertical cavity surface emitting lasers (VCSELs) and/or photodetectors, respectively. In the transmitter case, different VCSELs are operated at different wavelengths that change depending on a value of a condition such as temperature and/or one or more other parameters. Multiple VCSELs are assigned to each channel of the WDM. The currently active VCSEL is switched to a different VCSEL assigned to a same channel and preferably having an operating wavelength that is closer to the signal wavelength at the current measured or estimated temperature and/or other parameter value. Multiple photodetectors are assigned to each channel of the WDM, and currently active detector is switched to the second detector within the same channel. A tuning layer and a resonant waveguide grating coupler are preferably integrated into the resonant structure of the VCSEL array and wavelength specific detector array.

An optical coupler comprises first and second mirrors. The first mirror is positioned with respect to the second mirror so that a resonant cavity is defined between them. A waveguide structure is positioned in the resonant cavity and includes a photonic crystal coupler. A thickness of the resonant cavity is selected so that a phase matching condition is satisfied for resonance in the resonant cavity. At least one of the first and second mirrors may be formed from a structure in an optoelectronic device. Alternatively, at least one of the first and second mirrors is formed from a semiconductor layer. At least one of the first and second mirrors may be formed as a semiconductor distributed bragg reflector, or as a dielectric distributed bragg reflector. At least one of the first and second mirrors may be a mirror in a vertical cavity surface emitting laser (VCSEL) structure. The photonic crystal coupler structure may be shaped so that first order modes of light incident upon the photonic crystal coupler structure are coupled into the waveguide while zero-order modes are reflected out into the resonant cavity and reflected by the mirror.

A VCSEL waveguide grating coupler is provided such that a first and second mirror are positioned to define a resonant cavity between them. The waveguide grating coupler further includes a waveguide having a first grating formed as a part of the waveguide to couple light of a first polarization mode into the waveguide. A second grating is formed on the waveguide grating coupler and is orthogonal to the first grating. The second grating is operative to enhance the light coupled to the waveguide by creating a loss difference between light of the first polarization mode and light of a second polarization mode, so that light of the first polarization mode lases preferentially within the VCSEL.

A method of manufacturing a distributed Bragg reflector (DBR) in group III-V semiconductor compounds with improved optical and electrical characteristics is provided. A selected DBR structure is achieved by sequential exposure of a substrate to predetermined combinations of the elemental sources to produce a pair of DBR layers of compound alloys and a graded region including one or more discrete additional layers between the DBR layers of intermediate alloy composition. Exposure durations and combinations of the elemental sources in each exposure are predetermined by DBR design characteristics.

A simple yet high performance optical system is described which is tailored to enabling efficient detection of the luminescence emissions of near infrared-to-visible upconverting phosphors. The system is comprised of simple and relatively low cost optical components and is designed to telecentrically enable low optical power NIR excitation and high sensitivity VIS and NIR detection of the upconverting phosphor (UCPs), particularly the lanthanide doped UCP nanocrystals which show great promise for utility as molecular taggants in many applications of biomedicine, security and environmental monitoring. The overall system is designed to facilitate compact spectrophotometric instrument manufacture and is adaptable to multiple liquid or solid sample types and formats.
