| 标题： Octave-spanning Dispersion Manipulation and Its Applications in Silicon Nitride Slot Waveguide | |
| 摘要： Photonic integrated circuits (PIC) have attracted much interest recently. Silicon nitride (Si3N4) is a promising platform for PIC since it is compatible with CMOS technology. Furthermore, among different materials, Si3N4 is one of the primary choices to achieve on-chip supercontinuum source due to its reasonably high Kerr nonlinearity and negligible two-photon absorption (TPA). Slot waveguide is widely explored to tailor various properties for on chip elements, including dispersion manipulation. With the additionally introduced slot layer, chromatic dispersion can be efficiently tailored to be either low or high over broad bandwidth. This could be utilized to realize various linear or nonlinear optical signal processing functions. In this talk, we first review our recent design of Si3N4 slot waveguide with octave-spanning flattened dispersion. First, the proposed Si3N4 horizontal slot waveguide with SiO2 cladding can be used as a key dispersion element in an on-chip chirped pulse amplification system. 448× temporal broadening can be achieved for a 10-fs pulse after a 5-cm waveguide propagation. Together with the inherent low nonlinearity, it could be a key building block in on-chip chirped pulse amplification system with10-kW peak power. Second, we investigate the supercontinuum generation in the Si3N4 slot waveguide with all-normal dispersion. A > 400-nm flat and coherent supercontinuum is generated across E, S, C, L and U bands from 1355-1756 nm, by launching a 100-fs 10-kW hyperbolic secant pulse in a 5-mm Si3N4 slot waveguide with all-normal dispersion. | |
