A two-wavelength emission laser can be used to generate millimeter and terahertz waves by irradiating high speed photodiodes or nonlinear crystals. Recently, electro-magnetic waves at such frequencies have become important for high speed wireless communication and accurate sensing. The external cavity wavelength tunable quantum-dot (QD) laser is a candidate for fabrication of a two-wavelength emission laser because of its properties such as a simple structure, wide range of wavelength tunability, narrow linewidth, and emission wavelength stability. We have developed a QD wavelength tunable laser with a narrow linewidth and stable emission wavelength. In this study, we achieved two-wavelength emissions in the QD wavelength tunable laser by changing the external cavity configuration. |
