Can you give an idea?

In my project (manchester code decoding) I succeeded to decode the manchester coded data. but I'm getting the data by directly wiring the line to the MCU, my aim is to make it with a wireless method. I thought to use a LED (like in the circuit below) and another optical sensing device in front of the led. but my signal is 66KHz and I couldn't find a suitable optic sensor.

If anybody did a job like that please help me.

Can you compress the jpg attached, to obtain less than a 500kB file in order to have a ''free'' view? :D

will you please share your code ,rf card data was successfully coming at oscilloscope but i faled to decode it by using manchestor decoding

Most TV/VCR/CD etc.remote controls use IR LEDs and photodiodes operating at 30-60 kHz, so they will work at 66 kHz too. Try a discarded TV for both devices, they survive longest.
