The effects of bandwidth, gain, extinction ratio, shot noise and thermal noise … Photodetectors last for an indefinite period of time when used properly and within the specified specifications. The responsibility of a PIN diode is limited. Series PIN photodiode does not have a high-intensity electric field region. Erbium Doped Fiber Amplifier (EDFA) - 95% market! Thus, we propose to use a PIN array to receive the spatial light directly. Semiconductor photodiodes are commonly used to detect the optical signal in fiber optic communication systems, espacially pin-diodes and avalanche photodiodes. This DQPSK dual PIN photodiode has been incorporated in Yokogawa's PNTR404, the world's first RZ-DQPSK transponder. For these, InP/InGaAs/InP heteroepitaxial structures are required. MODELING THE FREQUENCY RESPONSE The structure of the PIN photodiode under investigation is shown in Figure 1 [2,5]. Si.
