Picosecond pulses are generated from a passively mode-locked ER3+/Yb3+ co-doped planar waveguide laser in an extended cavity configuration with a semiconductor saturable absorber mode locker. Average output power exceeds 8 mW and is expected to increase

Multimode Lasing at Room Temperature from InGaAs/GaAs Quantum Dot Lasers

Benjamin D. Klein, Kevin L. Silverman, Richard Mirin
We demonstrate InGaAs/GaAs quantuum dot lasers with multimode lasing at room temperature immediately above threshold. The lasing modes are separated by about ten times the Fabry-Perot mode spacing, with several dark modes in between the lasing modes. Rate

Single-frequency and Mode-locked Er/Yb Co-doped Waveguide Lasers

Berton Callicoatt, John B. Schlager, Kevin L. Silverman, Robert K. Hickernell, Richard P. Mirin, Norman A. Sanford, Joseph S. Hayden, Samuel D. Conzone, Robert D. Simpson
We present results for single-frequency and mode-locked Er/Yb co-doped waveguide lasers. The single-frequency DBR waveguide lasers have output power in excess of 80 mW with laser linewidth of 17 kHz. The passively mode-locked waveguide lasers produce

Compound semiconductor oxide antireflection coatings

K. J. Knopp, Richard Mirin, Kristine A. Bertness, Kevin L. Silverman, David H. Christensen
We report the development of high quality, broad-bandwidth, antireflection (AR) coatings using the low index provided by wet thermally oxidized Al 0.98Ga 0.02As. We address the design criteria, fabrication, and characterizations of AR coatings composed of
