Abstract

Numerical fitting reveals that the transmitting function of the filter used in this work can be described by the product of a Lorentzian function and the standard transmitting function of the filter. Using this filter as the tuning element of an external cavity semiconductor laser, a tuning range of ～20 nm from 1272.5 nm to 1291.7nm has been achieved.
