Abstract

We report the single-mode operation and characterization of a 1.3-m hybrid-fiber-tunable GaInNAs VCSEL. Results show that at room-temperature the device can be continuously tuned over 18.5-nm with output power up to 0.23-mW. Coupled-cavity effects were found to be a limiting factor for the tuning range. This device not only opens up potential applications in the physics of light-matter interaction, sensing and optical communications where it will, eventually, compete with InP-based VCSEL, but it is also a first step toward a tunable dilute-nitride vertical-cavity amplifier.
