The good optical transmission of hollow-core photonic crystal fiber and their relative low insertion loss in
conventional fiber network gave rise to a new type of all-fiber
gas-phase devices. These range from Raman converters
as laser sources, compact frequency standard devices for laser frequency control to electromagnetically-induced
transparency and saturable absorption for quantum optical devices. Here I report on the performance of these devices
and their prospects.
