Wooriro PD(Photo-diode) chips is Key components to detect or change optical(laser) signal to electrical signal. Photo diode has several important variables like responsivity, dark current, noise-equivalent power and etc. The Wooriro PD chips has high responsivity, low dark current, linear response for optical signal.     This PIN PD chips has very low dark current and capacitance. Using this chip an optical receiver with a high sensitivity is available.   1. Operation at 1.0 ~ 1.6µm 2. Low dark current and Capacitance 3. High responsivity 4. Linear response 5.

In addition, by designing their shot noise and Jonson noise current to be lower, they enable users to reduce minimum detectable signal. Their low dark current obtained in PD with large active area also guarantees high reliability. Thus, they can be used for reliable optical power requiring high resolution for a wide input optical power range.   1. High responsivity 2. Low dark current 3. Low Capacitance) 4.
