Patent ID: 6895144

Claim:
An optical power monitor comprising: a collimating means for collimating an incident light into a collimated beam; a dual fiber ferrule having an input optical port for receiving an incident optical beam to project to said collimating means, said dual fiber ferrule further having an output optical port for receiving an output optical beam reflected from said splitter/tapping means; a beam splitter/tapping means for transmitting a tapped portion of said collimated beam therethrough for measuring and monitoring an optical power wherein said beam splitter/tapping means comprising a splitter/tapping layer coated onto said collimating means; an optical signal detecting means for receiving said tapped portion of said collimated beam from said beam splitting/tapping layer for detecting an optical intensity; and a holding tube for holding said collimating means and said optical signal detecting means for securely fixing a relative position therein.
