MINT & WTMINT

Block diagram: WT-MINT

The incoming signal is split in two parts. One is delayed regarding the other and then both are recombined

on two outputs where they interfere one with each other. Both outputs are phase shifted by 180° and thus

can be plugged to balanced or differential photodiodes that will convert a phase modulation into an

amplitude modulation.

The delay between both arms of the interferometer should be equal to the time-bit (T

bit

) of the incoming

signal. Then the interferometer is characterized by its Free Spectral Range (FSR) which is linked to T

bit

by the

relation FSR=1/T
