Abstract
This work presents the design, fabrication and characterization of a Master Oscillator Power Amplifier (MOPA) quantum cascade laser in the mid infrared region. In this configuration, higher output power is achieved while maintaining a single transverse mode emission spectrum. The MOPA has been designed to display a single mode emission in continuous wave, at 9 µm wavelength, with a 12 dB amplification. These characteristics make it suitable for free space data transmission.
