Optical amplification is demonstrated in a two-dimensional photonic crystal. Amplification at 1575 nm is observed in the direction normal to the plane of periodicity, by pumping the device at 810 nm. A gain up to 27 dB is measured with moderate pump fluence (50 μJ/cm2). Gain is shown to clamp as laser threshold is attained.

    The article illustrates two laser-diode-clamp circuits. A standard junction field-effect transistor (JFET)-clamp circuit is effective for low-power semiconductor laser diodes but may not be so for diodes with power dissipation greater than 150 mA. If the laser is clamped during normal operation,...

    A definition of the term "laser" is presented. It refers to a device that emits a very narrow and intense beam of light or other radiation. The light is generated by exciting the atoms of a medium, such as a crystal, gas, or liquid. A laser emits a thin, intense beam of light that can travel...
