Notes:
Traditionally, mirror design at the wavelengths important for fiber optic systems (1.3 and 1.55 μm) has suffered from the low refractive index step available between InP and its lattice-matched alloys; the InP/In0.53Ga0.47As combination provides the largest index step, but at λ=1.55 μm absorption in the In0.53Ga0.47As layers degrades reflectivity. We have used the Burstein shift in n+:In0.53Ga0.47As to reduce the band-to-band absorption. This has yielded InP/In0.53Ga0.47As Bragg reflectors with reflectivity greater than 97%. These mirrors have been incorporated into a high-efficiency resonant-cavity photodetector operating at 1.55 μm. © 1996 American Institute of Physics.
