Abstract

We propose to design and develop 2x2 quad p-i-n InGaAs Photoreceivers having the following characteristics: (a) Active area diameter 0.75 mm; (b) Wavelength coverage 850 to 1700 nm, with responsivity of 0.7 A/W at 1064 nm; (c) Bandwidth up to 20 MHz for the individual quadrant; (d) Group Delay
