M. Li et al., DEMONSTRATION OF COMPUTER-GENERATED WAVE-GUIDE HOLOGRAM ON INGAASP-INP WAVE-GUIDE FOR 1550-NM OPTICAL WAVELENGTH, IEEE photonics technology letters, 9(7), 1997, pp. 958-960
We present experimental results on the first computer-generated wavegu
ide hologram based on an InGaAsP-InP waveguide for 1550-nm optical wav
elength. The potential of waveguide holograms as optical interfaces at
fiber optical communication wavelengths is demonstrated by the succes
sful operation of a waveguide-to-free-space fan-out element producing
a 4 x 4 spot array.
