WebFiber DFB lasers have been used successfully in a number of optical transmission system experiments. ... Figure 9 shows the bandwidth in the 1.48 μm absorption and 1.55 μm fluorescence spectrum of a typical erbium-doped ... Localized strain and/or temperature sensing is possible with very high sensitivity using two-mode DFB lasers, ... WebA form of mutually injection-locked lasers by butt coupling two distributed feedback (DFB) lasers with a high-Q microring resonator (MRR) is proposed and investigated. With the help of the MRR, two DFB lasers can achieve stable locking and carrier suppression output as the optical carriers and modulation sidebands are separated. The carriers of the lasers …

Web10 de abr. de 2024 · The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth. Such optical filtering is usually sophisticated and beyond the capability of the normal dielectric coating approach. Here we develop a 0.16 nm … Web1 de out. de 2024 · The bandwidth of the conventional DFB laser is 7.5 GHz and supports 10.5 Gb/s at room temperature.
