| titleOfInvention | Multi-wavelength laser system |
| abstract | (57) Abstract: The present invention provides a multi-wavelength light-emitting integrated planar waveguide device having a wide wavelength span, which can precisely control not only the absolute position and particularly the relative position of the emitted wavelength, but also the narrow line width. Systems and methods. The n eff caused by the laser mode in the waveguide is determined at least in part by the physical overlap between the laser mode of the waveguide core and the refractive index profile, the confinement factor. If the waveguide has a well-defined refractive index profile, adjusting the lateral dimension of the waveguide can adjust the refractive index profile, and thus the confinement factor and n eff . According to the invention, two or more guided lasers are formed, in which the reflecting member forming the laser cavity has a spatially dependent reflection determined by the effective refractive index n eff caused by the laser mode at the position of the reflecting member. Having a rate. By using the same reflective member, eg, a Bragg grating, for different lasers, the wavelength of the laser can be adjusted by adjusting the relative lateral dimensions, such as the width of the laser. This enables precise relative tuning of the laser and eliminates the uncertainty of the relative grating period of the Bragg grating. In order to widen the wavelength range by only slightly changing the width of the waveguide, it is preferable that n eff has a large dependence on the width w, n eff (w). Thus, different lasers will have approximately the same dimensions. |
