Abstract :
Summary form only. We present an electrically pumped GaAs-AlGaAs ridge waveguide laser using a focused ion beam (FIB) cut photonic band-gap crystal at the end of the cavity. A 1.35 mm long and 29 /spl mu/m broad ridge laser emitting at 9.4 /spl mu/m, has been cut twice, perpendicularly to the axis of the resonator. A one dimensional photonic bandgap crystal, formed of the two free-standing laser material plates and two air gaps is created on one of the ends. The other end of the laser is left unmodified.
