摘要： Tunable VCSELs (TVCSELs) employing expanded material systems with expanded mechanical/optical design space for semiconductor DBR mirrors on GaAs substrates. One is the InGaAs / AlGaAsP material system. It adds indium In to decrease InGaAs H-layer bandgap for higher refractive index and higher DBR layer refractive index contrast. Adding phosphorus P gives independent control of bandgap and strain of AlGaAsP low refractive index L-layers. The tensile strain of AlGaAsP L-layer compensates compressive strain of InGaAs H-layer and lowers the cumulative strain of the multilayer DBR structure. Another option is the InGaAsN(Sb) / AlGaAsP material system, where both types of layers can be lattice matched to GaAs. It uses indium In and nitrogen N, and possibly antimony Sb, to get independent control of strain and bandgap, and thus refractive index, of dilute nitride InGaAsN(Sb) H-layers, with lower bandgap and higher refractive index than starting GaAs. Using expanded material system enables reliable DBR mirrors with higher reflectivity and spectral bandwidth and tunable VCSELs with wider tuning range.

摘要： An illumination source includes a laser driver unit configured to emit a plasma sustaining beam. An ingress collimator receives the plasma sustaining beam and produces a collimated ingress beam. A focusing optic receives the collimated ingress beam and produce a focused sustaining beam. A sealed lamp chamber contains an ionizable media that, once ignited, forms a high intensity light emitting plasma having a waist size smaller than 150 microns. The sealed lamp chamber further includes an ingress window configured to receive the focused sustaining beam and an egress window configured to emit the high intensity light. An ignition source is configured to ignite the ionizable media, and an exit fiber is configured to receive and convey the high intensity light. The high intensity light is white light with a black body spectrum, and the exit fiber has a diameter in the range of 200-500 micrometers.

摘要： A semiconductor package is manufactured by physically attaching a side emitting laser diode to a floor portion of a recessed flat no-leads (FNL) package having a wall extending from and surrounding a perimeter of a recessed floor portion. The attached side emitting laser diode is oriented to direct a laser beam toward an opposing portion of the wall. The FNL package is singulated into a first piece and a second piece along a singulation plane through the FNL package wall and floor portion between the side emitting laser diode and the opposing portion of the wall. After singulation the opposing portion of the wall is in the second piece and the side emitting laser diode is in the first piece.

摘要： A light source providing multi-longitudinal resonant waves, particularly by utilizing an optical parametric oscillator (OPO) to produce a broadband emission spectrum. By configuring the system to pump the OPO far above the oscillation threshold, tunable light of macroscopic power with a short coherence length is provided. The coherence may be further shortened by additional longitudinal mode scrambling.

摘要： A high power microscopy illumination system is disclosed, having a liquid cooled, Solid State Light Source (SSLS) unit including one or more LED light sources, thermally mounted on a cold plate, which is cooled by a closed-loop liquid cooling system including a remote unit housing a heat exchanger. The SSLS unit with the LED light source is compact and lightweight, and is mechanically and optically directly coupled to the illumination port of the microscope, for efficient optical coupling to the imaging plane. High capacity cooling of the LEDs, enables the LEDs to be driven at higher current densities for increased optical output and for operation with improved thermal stability. The LED driver circuitry may also be housed within the SSLS unit and liquid cooled. The SSLS unit is vibrationally isolated from vibration-causing components of the cooling system, such as cooling fans and other bulky components, which are housed in the remote unit.
