Method of determination of the emission wavelength of the cavity semiconductor lasers fabry perot - using electrical measurements.

摘要

The lasers being formed on a same plate a semi - conductive, it determines the optically the emission wavelength lambda1 of one of the lasers. The emission wavelength lambda of each other laser is determined by the electrical measurements on the current i injected into the laser and the voltage v between its terminals, and with the formula λ = delta + v rxi 1,24x (-) - 1, where r is the dynamic resistance of the laser, for i greater than the threshold current of the laser. It determines delta with this formula is applied to the laser, the emission wavelength is lambda1. Application in optical telecommunications.
