Abstract
An optical system comprises a low coherence light-emitting device and a mirror. The mirror is positioned adjacent an end face of the device such that light emitted from the end face may be redirected back into the device. Radiation having low coherence, which is emitted from an opposing end face, is amplified greatly due to the radiation which reenters the device.
Claims7
In a low coherence optical system having a low coherence light-emitting device which includes a semiconductor body with an optical path therein and first and second end faces, the improvement comprising:
- means for redirecting radiation positioned adjacent said second end face such that at least a portion of the radiation emitted from said device is redirected so as to reenter the device, said redirecting means being also positioned such that a resonant cavity is not formed between said means for redirecting radiation and said first end face.
