  • Laser diode facet coating
    Patent number: 5812580
    Abstract: A multi-layer high reflective dielectric optical coating deposited on a laser diode facet that shifts the high amplitude peak of the electric field associated with the reflection of light away from the interface between the semiconductor material and the reflective coating, and into the reflective coating itself. By shifting the electric field peak in this manner, the laser diode can operate at much higher optical output powers without inducing catastrophic optical damage at the non-output facet.

  • Monolithic wavelength meter and photodetector using a wavelength dependent reflector
    Patent number: 5760419
    Abstract: A compact and cost-effective wavelength meter and photodetector (10) that can measure simultaneously both wavelength and intensity has two back-to-back photodiodes (12 and 14) with a wavelength dependent distributed Bragg reflector (DBR) (28) positioned in-between. The wavelength resolution of this device is 1 nm or less. Easy design and fabrication of the device provides for reliable and cost-effective manufacturing. Applications include instrumentation and wavelength-division-multiplexing (WDM) in optical communication systems.
