A spectroscopy system comprising at least two laser modules, each of the laser modules including a laser cavity, a quantum cascade gain chip for amplifying light within the laser cavity, and a tuning element for controlling a wavelength of light generated by the modules. Combining optics are used to combine the light generated by the at least two laser modules into a single beam and a sample detector detects the single beam returning from a sample.

QCL spectroscopy system and applications therefor

Method and apparatus for mounting an optical fiber for coupling to a high power light source, the fiber being secured to its mount with a low refractive index adhesive. The low refractive index adhesive serves to reduce the coupling of light traveling within the fiber to the fiber mount, thereby reducing undesirable, potentially destructive heating in the fiber mount. The adhesive preferably comprises sol gel.

Reducing heating from non-coupled light in power transmitting optical fibers

An opto-mechanical platform for supporting truncated optical elements having at least one substantially flat side surface is disclosed. In one particular exemplary embodiment, the opto-mechanical platform may be realized as an apparatus for supporting truncated optical elements having at least one substantially flat side surface. Such an apparatus may comprise a platform having a substantially flat surface area for supporting the substantially flat side surface of the truncated optical elements. Such an apparatus may also comprise at least one substantially vertical wall formed on at least a portion of the platform for providing mechanical rigidity to the platform.

Opto-mechanical platform

A wavelength division multiplexer (WDM) including a support structure that is coupled to at least one optical component. A diffraction grating is optically coupled to at least one optical component coupled to the at least one optical component. A frame is coupled to the diffraction grating. Pins may be coupled between the support structure and the frame to substantially thermally isolate the support structure from the frame. The pins may be substantially geometrically equally spaced and have approximately the same exposed length extending from the lens barrel. The pins may have the same coefficient of thermal expansion as the support structure.

Thermally stable mounting for a diffraction grating device

An improved diffraction grating for wavelength division multiplexing/demultiplexing devices is disclosed. The improved diffraction grating has a glass substrate, a polymer grating layer located adjacent to the glass substrate, and a metal coating layer located adjacent to the polymer grating layer. The improvement comprises a polymer coating layer located adjacent to the metal coating layer, and a glass cover located adjacent to the polymer coating layer, wherein the polymer coating layer and the glass cover compensate for thermal characteristics associated with the polymer grating layer and the glass substrate, respectively.
