Wavelength-spacing tunable multi-wavelength source by controlling the intermodal transitions induced via dynamic reconfiguration of a nested photonic crystal cavity, through optically induced free carriers, is proposed. Optical combs spanning the entire C-band are demonstrated numerically.
Multi-wavelength Generation, by intermodal transitions induced via dynamically reconfiguring a heterostructure cavity embedded within a photonic crystal ring resonator, is proposed. Tailoring the structure, 13 generated frequencies spanning the S-L bands are demonstrated numerically.
Wavelength conversion over 90 nm around 1550 nm is demonstrated numerically through intermodal transition by uniformly tuning a proposed nested photonic crystal cavity. Discontinuity of the initial state and modal symmetry suppresses the adiabatic and multiple transitions.
We present analysis of a superprism design wherein simultaneous wavelength separation and diffraction compensation in slab results in an enhanced effective angular dispersion and considerable reduction in chip footprint when compared to the preconditioned superprism.
A superprism design is proposed whereby simultaneous wavelength separation and diffraction compensation in the slab region considerably shrinks the area required when compared to the preconditioned superprism design. All-parallel, diffraction-limited outputs obviate the focusing optics.
We propose a nested photonic crystal cavity configuration for on-chip wavelength conversion based on adiabatic tuning of the resonator whereby dynamic switching between two cavity structures significantly extends the achievable frequency conversion range.
Based on the concept of mode-gap confinement, we propose a cross-shaped heterostructure photonic crystal cavity incorporating an intersecting waveguide for direct in-plane pumping of the cavity via the mode of the crossing waveguide.
