ABSTRACT:
A superluminescent diode has one end coupled to a DBR having a grating and the other end has a reflective coating. A broadlight spectrum is emitted for reduced speckle interference and phase noise when used in applications such as a gyroscope. The diode can be of the "P side down" type for good heat dissipation during continuous wave operation. Two gratings can be used in order to reduce beam divergence.
