- •
Novel GaInNAs RCEPD for the 1.3 渭m optical communications window.
- •
Without internal gain we obtain a 43% quantum efficiency.
- •
With internal gain we obtain 67% quantum efficiency at a very low bias voltage of V = −2.5 V.
- •
Excellent wavelength selectivity with FWHM of the cavity resonance of 5.0 nm.
- •
Very low dark current at 300 K of 1.7 nA at −1 V, increasing to 6.5 nA at −2 V.
