J. Yoo et al., EXPERIMENTAL DEMONSTRATION OF A 4-PLANE 2-D MULTIPLE-WAVELENGTH OPTICAL INTERCONNECTION USING INTEGRATED VCSEL ARRAYS AND MQW DBR DETECTORS/, IEEE photonics technology letters, 9(12), 1997, pp. 1646-1648
We experimentally demonstrate a four-plane two-dimensional (2-D) wavel
ength-division multiplexed (WDM) optical interconnection using integra
ted multiple-wavelength WDM transmitting VCSEL arrays and three-wavele
ngth-selective detector arrays, The detector planes employ multiquantu
m-well (MQW) detector arrays, with the middle plane being a novel chan
nel-dropping detector with a single mirror resonant cavity, This middl
e plane provides superior wavelength selectivity thereby reducing cros
stalk from the shorter and longer wavelength channels, Reconfigurable
and simultaneous WDM interconnections between planes are demonstrated
at 155 Mb/s.
