T. Coroy et al., ACTIVE WAVELENGTH MEASUREMENT SYSTEM USING AN INGAAS-INP QUANTUM-WELLELECTROABSORPTION FILTERING DETECTOR, IEEE photonics technology letters, 8(12), 1996, pp. 1686-1688
A novel wavelength measurement system based on an InGaAs-InP multiple
quantum-well electroabsorption filtering detector has been demonstrate
d. The tunable wavelength response of the filtering detector is used i
n an active manner to track the wavelength of a spectrally narrow inpu
t optical signal. An average resolution of +/-8.30 pm was achieved, ov
er a measurement range of 43 mn.
