Abstract: An on-chip bidirectional pulse compressor for temporal compression and spectral compression. The on-chip bidirectional pulse compressor including a substrate; a nonlinear waveguide disposed on the substrate, wherein the nonlinear waveguide is dimensioned to induce a nonlinear response within a predetermined operating wavelength ranges and is made of a material free of two-photon absorption at the predetermined operating wavelength ranges; and an anomalous dispersive component disposed on the substrate. The nonlinear waveguide and the anomalous dispersive component are interconnected for bidirectional pulse propagation, wherein propagating through the nonlinear waveguide followed by the anomalous dispersive component causes temporal compression, and propagating through the anomalous dispersive component followed by the nonlinear waveguide causes spectral compression. Various embodiments also include an optical device including the on-chip bidirectional pulse compressor.
