Abstract: A wideband light source includes multiple light sources enclosed within a butterfly package. The butterfly package includes light sources of different types such as a plurality of SLEDs and a plurality of laser diodes. Other types of broadband and narrow band light sources may be included on the same butterfly package in a similar manner. The emitted light from each light source is collimated via a collimating lens and directed towards an optical fiber using a mirror. Each light source produces light in a different spectral range, and the collimated beams from the various light sources are combined into a joined broadband beam by a plurality of corresponding dichroic mirrors. The broadband beam is coupled into a single mode or polarization maintaining fiber which serves as the optical output from the butterfly package. A processor monitors the power output of each light source drives each light source to ensure stability.

Abstract: A Fourier Transform Infrared (FTIR) Spectrometer integrated in a CMOS technology on a Silicon-on-Insulator (SOI) wafer is disclosed. The present invention is fully integrated into a compact, miniaturized, low cost, CMOS fabrication compatible chip. The present invention may be operated in various infrared regions ranging from 1.1 ?m to 15 ?m or it can cover the full spectrum from 1.1 ?m to 15 ?m all at once. The CMOS-FTIR spectrometer disclosed herein has high spectral resolution, no movable parts, no lenses, is compact, not prone to damage in harsh external conditions and can be fabricated with a standard CMOS technology, allowing the mass production of FTIR spectrometers. The fully integrated CMOS-FTIR spectrometer is suitable for battery operation; any and all functionality can be integrated on a chip with standard CMOS technology. The disclosed invention for the FTIR spectrometer may also be adapted for a CMOS-Raman spectrometer.
