Hi everyone,
Yeah, i also agree that responsivity and sensitivity are not same.
The responsivity is usually defined for the steady state.
responsivity as the ratio of output voltage and optical power.
The photodiode response typically falls off for signal frequencies above some detection bandwidth.
while sensitivity is sensitivity is the lowest detectable light level,
which is typically determined by detection noise and significantly influenced by the required detection bandwidth.

Thanks for suggestion and response.
