The G11097-0707S has a hybrid structure consisting of a CMOS readout circuit (ROIC: readout integrated circuit) and back-illuminated InGaAs photodiodes. Each pixel is made up of an InGaAs photodiode and a ROIC electrically connected by an indium bump. A timing generator in the ROIC provides an analog video output and AD-TRIG output which are easily ob-tained by just supplying a master clock (MCLK) and master start pulse (MSP) from external digital inputs.The G11097-0707S has 128×128 pixels arrayed at a 50 μm pitch and their signals are read out from a single video line. Light incident on the InGaAs photodiodes is converted into electrical signals which are then input to the ROIC through indium bumps. Electrical signals in the ROIC are converted into voltage signals by charge amplifi ers and then sequentially output from the video line by the shift register. The G11097-0707S is hermetically sealed in a metal package together with a one-stage thermoelectric cooler to deliver low-cost yet highly stable operation.
