摘要：

A 1.5 μm tunable two-section laser diode with external grating feedback has been investigated. A very broad-band (154 nm) tunable range has been achieved by means of an optimized anti-reflection (AR) coating and a large NA lens coupling between the LD and the grating. We attempted to control the internal mode by use of a two-section LD which has a phase-control section. Consequently, single-mode lasing has been realized at any desirable wavelength within the 154 nm range. © 1990 IEEE
