Abstract:
Systems, devices, and methods for narrow waveband laser diodes are described. The conventional coating on the output facet of a laser diode is replaced with a notch filter coating that is reflective of wavelengths within a narrow waveband around the nominal output wavelength of the laser diode and transmissive of other wavelengths. The notch filter coating ensures the laser diode will lase at the nominal wavelength and not lase for wavelengths outside of the narrow waveband. The notch-filtered laser diode provides a narrow waveband output that is matched to the playback wavelength of at least one hologram in a transparent combiner of a wearable heads-up display, and thereby reduces or eliminates display aberrations that can result from wavelength sensitivity of the playback properties of the hologram.

Claim (Index 1):
A laser diode comprising:\n a layer of p-type semiconductor material; a layer of n-type semiconductor material; a layer of optically active material disposed between the layer of p-type semiconductor material and the layer of n-type semiconductor material; a reflective rear facet at a first end of the layer of optically active material; a partially reflective output facet at a second end of the layer of optically active material, the second end opposite the first end across a length of the layer of optically active material to define a laser cavity at least partially bounded by the layer of p-type semiconductor material, the layer of n-type semiconductor material, the reflective rear facet, and the partially reflective output facet; and at least one notch filter coating applied to at least one of the reflective rear facet and the partially reflective output facet.
