Popis: | We studied wavelength stabilized all-epitaxial 970nm spectral range GaAs∕GaAlAs tilted cavity lasers (TCLs). Single transverse mode edge-emitting 4-μm-wide ridge lasers demonstrated spatial and spectral single mode continuous wave operation with a longitudinal side mode suppression ratio up to 41.3dB. Small signal modulation bandwidth of 3GHz with a resonance peak of 6dB at the relaxation oscillation frequency was measured for a 870μm long device. TCL modulation efficiency is 0.36GHz∕(mA)1∕2. S-parameter measurements indicate that much higher frequencies may be expected in case of more advanced processing and/or shorter cavity lengths. |
