Abstract

AbstractWe demonstrate spectral narrowing with broadband tuning from a picosecond self‐injection‐seeded gain‐switched diode laser. A narrowband spectral output was continuously tunable over a range of 44 nm from 1.538 to 1.582 μm. We also observe a gain‐switched hybrid‐operation regime with elements of mode‐locking. Our numerical simulations exhibit good agreement with the experimental results. © 2004 Wiley Periodicals, Inc.
