thank you aabid baba and aasif basir,,,,
the link provided above shows the basic implementation of reversible logic gates using Mach Zehnder interferometer (MZI) switches,,,,,,,
i am quiet familiar with that as i had already posted in question that i need to improve the power consumed by the circuit, its efficiency in terms of fast switching and ease of fabrication,,,,
so kindly suggest me some alternative ways to achieve the desired results,,,,
thanking you in advance,
with regards
