WebSimilar processing techniques can be used for fabrication of single mode lasers operating in the 2 μm wavelength range. NTT-Japan demonstrated a DFB laser with an emission wavelength of 2.051 μm and output power of 10 mW . A schematic of their buried heterostructure DFB grating is shown in Figure 5. The DFB grating was buried and … WebFabrication methods of EMLs include selective area growth, [3 ]butt-joint,4 identical active layer5 and quantum well intermixing[6] etc. Selective area growth (SAG) is a simple method to integrate elec-troabsorption modulator (EAM) and a distributed feedback (DFB) laser. By using SAG, the multi-quantum wells (MQWs) with different band-gap en-
WebJul 15, 2013 · For the fabrication of DFB laser arrays, two thin p doped and n doped InGaAsP layers were grown successively on the upper SCH layer and a grating with uniform pitch was formed on the entire wafer by holographic lithograph. The reverse junction in the InGaAsP layer induces a weak gain coupling into the DFB structure, which helps to … WebAn alternative method for DFB fabrication makes use of Bragg gratings etched alongside a ridge waveguide to form a laterally coup led distributed-feedback (LC-DFB) laser. 3 This approach enables fabrication of single-longitudinal-mode lasers following a single epitaxial growth process. However, all the demonstrated lasers to-
