CMOS-compatible 75 mW erbium-doped distributed feedback laser.
On-chip, high-power, erbium-doped distributed feedback lasers are demonstrated in a CMOS-compatible fabrication flow. The laser cavities consist of silicon nitride waveguide and grating features, defined by wafer-scale immersion lithography and an erbium-doped aluminum oxide layer deposited as the final step in the fabrication process. The large mode size lasers demonstrate single-mode continuo...

On chip, high power (75mW), erbium-doped distributed feedback lasers are demonstrated in a CMOS compatible fabrication flow. The laser cavities consist of silicon nitride waveguide and grating features defined by wafer-scale immersion lithography and a top erbiumdoped aluminum oxide layer deposited as the final step in the fabrication process. 2013 Optical Society of America OCIS codes: (130.0...
متن کاملSpectral correlations in a random distributed feedback fibre laser
Random distributed feedback fibre lasers belong to the class of random lasers, where the feedback is provided by amplified Rayleigh scattering on sub-micron refractive index inhomogenities randomly distributed over the fibre length. Despite the elastic nature of Rayleigh scattering, the feedback mechanism has been insofar deemed incoherent, which corresponds to the commonly observed smooth gene...
متن کاملDistributed feedback photonic crystal fibre (DFB-PCF) laser.
A distributed feedback laser is fabricated in Er3+-doped photonic crystal fibre. Preferential single-mode lasing is obtained with no special consideration of polarisation issues. The results demonstrate practical implementation of a multi-photon writing process for complex structures in these optical fibres. No hydrogen loading and no germanium are involved.
متن کاملDistributed ultrafast fibre laser
A traditional ultrafast fibre laser has a constant cavity length that is independent of the pulse wavelength. The investigation of distributed ultrafast (DUF) lasers is conceptually and technically challenging and of great interest because the laser cavity length and fundamental cavity frequency are changeable based on the wavelength. Here, we propose and demonstrate a DUF fibre laser based on ...
