how to convert from optical signal to electrical signal in optisystem

[communication]

hi guys
can any one help me to to convert from optical signal to electrical signal OR from electrical signal to optical signal in optisystem

I think i can give u a basic. photo detector is reqd to convert light to electrical signal
an APD(avalanche photo Diode ) can do this job it'll give a current signal then it's to be passed thru a voltage devider nw and by amplifying a voltage signal can be obtained .

these can easily done by optoelectronic devices.
optical to electrical converters are photodiode and phototransistors.
electrical to optical conversion is most frequently used in fiber optics communicaions. Light emitters are a key element in any fiber optic system. This component converts the electrical signal into a corresponding light signal that can be injected into the fiber.

i already done all. i used LED to send the signal & received by photo diode, however when i received the signal using photo diode the light signal converted to electric signal. i want to convert this electric signal to light signal.
tnx
