We show that optimal {\textquotedblleft}quantum-limited{\textquotedblright} conversion efficiency can be achieved at any pump power when the powers at the pump and idler frequencies satisfy a critical relationship. We demonstrate the existence of a broad parameter range in which all triply-resonant DFG processes exhibit monostable conversion. We also demonstrate the existence of a geometry-dependent bistable region.}, year = {2009}, journal = {OE}, volume = {17}, number = {11}, pages = {9241{\textendash}9251}, url = {http://www.opticsinfobase.org/oe/abstract.cfm?URI=oe-17-11-9241}, }
