Title: Driver circuit for a laser
Inventor: KAISER NORBERT
IPC: H01S5/042
Filed: 1993-03-15
Granted: 1999-02-02
Abstract: Prior  art  driver  circuits  are  implemented  with  a differential   amplifier   which   is   adapted   to   the characteristics of the respective laser and optimized for maximum emitter-current density of the transistors.   At small currents, these circuits exhibit a degraded pulse response.  The object was to provide a driver circuit whose pulse response is essentialy independent of the modulating-current range.   To attain this object,  a differential amplifier  has  at  least  one  additional  differential amplifier connected in parallel therewith.   The current source  associated  with  the  respective  differential amplifier is switched on digitally or continuously via a control   circuit,   depending   on   modulating-current requirements.  Each of the parallel-connected differential amplifiers delivers a fraction of the modulating current. By distributing the modulating current to two or more differential  amplifiers,  a better pulse  response  in a greater current range than in the prior art is achieved. The driver circuit is universally applicable to lasers with differents characterics in optical communication systems.
