how to make IrDA from simple circuit bcoz. i don't have IrDA module
 

just need a photodiode and an IR led

you just need an IR Led for transmiter and a photodiode for reciver.
This way you can build the electrical interface of IRDA.
Next, you need to write a few lines of code yn your mcu for inplement a much like software uart. Main difference are that IRDA signals are Zero Return (ZR) insted of RS232, wich are Non Zero Return (NZR).

I've implemented IRDA in a PIC16f84@4Mhz and it works very well

Look at Philips Semiconductors for IRDA details.

good luck
