%X The temporal response of an optical integrated device is theoretically analysed. The device is composed of a Metal-Semiconductor-Metal (MSM) Photodetector and a Light Emitting Diode (LED). The analysis is based on the frequency response of the constituent devices without any optical feedback within the device structure. All expressions describing the frequency response, time response, output derivatives, and rise time are outlined. The results show that the temporal response of MSM detectors is similar to the LED response if the cutoff frequency of the LED is lower than that of MSM, while it is similar to MSM detector if the cutoff frequency of the MSM is lower than that of LED.
