  • Optical apparatus using multi-wavelength light
    Patent number: 10904971
    Abstract: An optical apparatus using multi-wavelength light, includes a substrate, and a light emitting array disposed on the substrate, and comprising a plurality of light emitting devices emitting a plurality of lights having different wavelengths. The optical apparatus includes a controller configured to control the light emitting array such that the plurality of lights are modulated differently and emitted simultaneously.

  • Method of forming a tapered section in a semiconductor device to provide for reproducible mode profile of the output beam
    Patent number: 6174748
    Abstract: A method for fabricating a high power laser diode device with an output emission with a nearly circular mode profile for efficient coupling into an optical fiber. A vertical taper waveguide and a window tolerance region are formed in a base structure of the device employing successive etching steps. Further regrowth completes the device structure. The resultant laser device has a vertical and lateral tapered waveguide that adiabatically transforms the highly elliptical mode profile in an active gain section of the device into a substantially circular mode profile in a passive waveguide section of the device.
