Researchers have developed a compact ultra-broadband electro-optic comb that fits into a chip smaller than a coin. The device achieves an impressive 450 nm of light precision, boosts bandwidth ...

But building compact and efficient frequency combs has been a challenge—until now. Electro-optic frequency combs, introduced in 1993, showed promise in generating optical combs through cascaded ...

Andrew Weiner and co-workers from the USA now demonstrate a reconfigurable and tunable flat-top microwave photonic filter using an electro-optic frequency comb and a dispersive medium, in which ...
