WAVELENGTH TUNABLE EXTERNAL CAVITY LASER |
摘要 |
<p>Provided is a wavelength tunable external cavity laser comprising: a semiconductor laser diode that outputs multi-wavelength optical signals and is mounted on a first substrate; and a wavelength tunable reflection filter that is mounted on a second substrate, outputs single wavelength optical signals among the multi-wavelength optical signals using resonance of external cavity formed between a semiconductor laser diode and a Bragg-grating having a predetermined period, and tunes the wavelength of the output single wavelength optical signal by varying the refractive index of the Bragg-grating. The wavelength tunable Bragg-grating reflection filter and the semiconductor laser diode are mounted on separate substrates, and the optical coupling efficiency between the semiconductor laser diode and the waveguide type Bragg-grating reflection filter is increased using an active alignment method to increase the optical output power and enable a stable oscillation mode.</p> |
