Td. Liao et al., DEMONSTRATION OF GUIDED-WAVE OPTICAL FAN-OUT USING WAVE-GUIDE DIFFRACTIVE OPTICAL-SYSTEM, Optics communications, 137(1-3), 1997, pp. 1-5
Guided-wave two-dimensional optical fan-out has been experimentally de
monstrated by using a waveguide diffractive doublet consisting of a un
iform grating coupler and a diffractive optical element. Design of thi
s waveguide diffractive doublet and device fabrication results are als
o presented.
