A fiber-loop laser with a cooled erbium-doped section
Eyal Buks, Boris A. Malomed
An optical comb featuring an unusual structure has been recently observed in a fiber-loop laser running at cryogenic temperatures. In the present work, the effect of optical polari…

Polarimeter optical spectrum analyzer
Eyal Buks
A coherent optical spectrum analyzer is integrated with a rotating quarter wave plate polarimeter. The combined polarimeter optical spectrum analyzer (POSA) allows the extraction o…

Intermode coupling in a fiber loop laser at low temperatures
Eyal Buks
We experimentally study an unequally-spaced optical comb (USOC), which is generated by a unidirectional fiber loop laser operated at low temperatures. The underlying mechanism resp…
