| Title: | Tunable dual-wavelength picosecond pulse generation by the use of two Fabry-Pérot laser diodes in an external injection seeding scheme | Authors: | Zhang, M Wang, D Li, H Jin, W Demokan, S |
Issue Date: | Jan-2002 | Source: | IEEE photonics technology letters, Jan. 2002, v. 14, no. 1, p. 92-94 | Abstract: | An attractive alternative to generate tunable dual-wavelength pulses by external injection seeding of a gain-switched Fabry-Pérot laser diode (FP-LD) is demonstrated. The external-injection-seeding branch consists of only a FP-LD, a 3-dB coupler and two fiber Bragg gratings (FBGs). The two wavelengths can be selected and their spacing can be tuned by adjusting two FBGs. The output sidemode-suppression-ratio is better than 17 dB over a 10-nm wavelength tuning range. The whole system is simple and of low cost. | Keywords: | External injection seeding Gain switching Picosecond pulse |
