Fine tuning of conversion/dispersion based optical delays with a 1 pm tunable laser using cascaded acousto-optic mixing.
We demonstrate a technique for fine tuning of optical delays using cascaded acousto-optic modulators to improve the delay resolution by 5 orders of magnitude compared to a 1 pm tunable laser. A 256 ns delay with <0.5 ps resolution is shown for 40 Gbits/s return-to-zero on-off keying with no added penalty.
