A. B. Miller,"Misalignment-Tolerant Surface-Normal Low-Voltage Modulator
for Optical Interconnects," IEEE J. Selected Topics in Quantum
Electronics, 11, No. 2, 338 – 342 (March/April 2005)
We present
a surface-normal modulator architecture for optical interconnects that
offers misalignment tolerance as well as high contrast ratio over a wide
wavelength range for a small drive voltage. A contrast ratio greater
than 3 dB was achieved for only 0.8 V drive across a 16 nm wavelength
range from 1498 nm to 1514 nm. The misalignment tolerance between this
device and the input optical beam was measured to be 30
mm. |
