ABSTRACT We numerically investigate the potential of Al2O3:Er3+ active slot waveguides for realizing small-form factor lasers on silicon-on-insulator. Based on recent technological improvements in the reliable and low-cost fabrication of alumina doped with high Er3+ concentration, we point out the possibility of realizing silicon compatible emitters at 1.55 μm, optically pumped at 1480 nm with a few milliwatts threshold pump power.

    ABSTRACT: We numerically investigate the potential of Al O :Er active slot waveguides for realizing small-form factor lasers on silicon on insulator at 2.8 m. Based on re- cent technological improvements in the reliable and low-cost fabrication of alumina doped with high Er concentration and exploiting the extremely high field intensity achievable in optimized active slot waveguides, we point out the possibility of realizing silicon-compatible emitters at 2.8 m, optically pumped at 1480 nm with a few milliwatts threshold pump power. A strong potential impact can be envisaged for chemical sensing, biosensing and lab-on-a-chip applications. Index Terms—Aluminum oxide, erbium, integrated optics, slot waveguide, 3 m laser.

    ABSTRACT: Design of a compact polarization rotator (PR) exploiting power coupling through phase matching between the TM mode of a strip waveguide (WG) and TE mode of a vertical slot WG is presented. Optimized cross sectional dimensions of the coupler have been achieved to use this device as a compact PR at 3 µm wavelength with device length of just 2 mm. We also investigate the device performance at the operating wavelength (λ) = 1.55 µm.
