However, the direct use of silicon in ultraviolet field is prevented by its narrow band gap. The lack of specific absorption for UV light makes silicon inevitably affected by visible and infrared light, curtailing the spectrum selectivity. Attaching a filtering apparatus leads to more complexity, low integration and poor portability of detectors .

Silicon is only weakly absorbing over the wavelength band 0.8 – 0.9 m. This is because transitions over this wavelength band in silicon are due only to the indirect absorption mechanism. The threshold for indirect absorption (long wavelength cutoff) occurs at 1.09 m. The bandgap for direct absorption in silicon is 4.10 eV,

The cutoff frequency of the low-pass filter is equivalent to the width of a band- pass filter around the modulation frequency. For example, if the modulation frequency is 5 kHz and you use a low-pass filter with bandwidth of 10 Hz, the output of the circuit would pass signals from 4.99 kHz to 5.01 kHz.
