Standing Wave Pattern," Appl. Phys. Lett. 76, 3185-3187 (2000)
.We demonstrate a wavelength monitor and a two-wavelength detector based
on two single-quantum-well absorbers that sample a standing wave created by a distributed
Bragg reflector. As a wavelength monitor, our device is power independent over a 15 dB
range. Wavelength discrimination is linear over a 12 nm range.
