Abstract
PURPOSE: To obtain monitor beams proportional to signal beams , by branching one portion of the signal beams from a laser diode by means of a beam splitter, and by making the laser luminous polarization surface and an incident surface to the beam splitter perpendicular.
CONSTITUTION: When beams from a laser diode 1 are collected to a photo-fiber 4, one portion of signal beams is branched by means of a beam splitter 5 inserted between lenses, and collected to a beam receiving element 7 for monitor. In this case, the quantity of beams branched depends upon relative locations between a laser luminous polarization surface 8 and an incident surface 9 to the beam splitter 5, and monitor beams are gained only when both are perpendicular. When the monitor output is used and an APC loop is formed, this luminous device that has small level variation to the change of temperature, a secular change, etc. can be obtained.
