Actually I want to modulate the data on laser and for that I need a fast switching transistor. So I wanna know how many number of bits I can transfer by the switching of transistor if it has total time period of 20ns...I know the frequency I get is 50MHz...but is the bit rate 50Mbits/s
what is the speed of transister

what parameter of transistor must b matched with the wavelength of laser.....lets say if my laser has a wavelength of 670nm then wat kindaphototransistor do i hv to use?
Re: Laser communication
wud u plz elaborate how frequency modulator can b used. anything above 1mb-50mb wud b sufficient.....Actually my task is to transfer files with different extensions and audio files....
Hi,
My project is laser communication network. n I m getting data frm pc through serial port. But the prob is, UART (max232) restricts the data to much lower speed than 120kps which is serialports max speed.... also I wana knw the fast switching transistors for laser switching....can...
