23. The photocurrent of detector arrays was characterized using a low noise current preamplifier and a lock-in amplifier. A 150 W Xe lamp with 1200 line/mm grating monochrometer was used as the light source. The typical bias voltage for the detector is 5 V.
24. For monolithic microspectrometer applications, sharp photon response edge to the right of the peak is more desirable since it allows higher wavelength resolution. Thus, we use the right half width at half maximum.
