摘要： A shunt driver for driving an LD is disclosed. The shunt driver has the push-pull arrangement with the high side driver and the low side driver. The high side driver is driven by a positive phase signal superposed with a negative phase signal with a delay and a less amplitude with respect to the positive phase signal. The low side driver is driven by a negative phase signal superposed with a positive signal with a delay and a less amplitude compared to the positive phases signal. Adjusting the magnitude of the superposed signals, the driving current for the LD has the peaking in the rising and falling edges thereof.

摘要： A device and a method enabling the enhancing of the modulation efficiency of lasers by matching the modulation frequency and the FSR of the laser. This is optionally achieved by eliminating the internal cavity of a laser diode (103) placed in an external cavity and matching the FSR of the external cavity to the modulation frequency. The modulation index is enhanced to and beyond the point of complete carrier suppression even at high modulation frequency and high beam intensities. The external cavity comprises a grating (107), the cavity length being adjusted with a PZT (108) and a translation stage (109). The laser diode (103) is driven by a bias current (110) from a driver (115) and a modulation current (111) from a modulation driver (116).
