<p>A miniature ultra-short light pulse source is based on a passively mode-locked semiconductor laser, including a multisegment laser diode (LD) with controllable saturation in absorbing sections(s) and anti-reflection coating on one of its facets, which is used as an active element. A single-mode optical fiber with a Bragg grating (FBG) written into its core is used as an external cavity. Depending on FBG reflectivity spectrum, the device emits a regular train of transform-limited ps-length pulses or linearly chirped ps-length pulses suitable for a time-compression technique.</p> |
