A silicon optical diode enables optical non-reciprocity through direction-dependent resonance shift of microrings based on the thermo-optic effect in silicon. We observe an ultra-high nonreciprocal transmission ratio of 40 dB with an improved design of the optical diode. One-way 10Gbps data transmission is realized based on the strong dispersion and attenuation associated with a resonant structure.
We design and fabricate a simple ultracompact wavelength-controllable bi-directional optical diode. It consists of a silicon microring (nonlinear attenuator) and a directional coupler (linear attenuator). High nonreciprocal transmission (∼24.2dB) is achieved. Negligible-penalty OFDM/OAM 64-QAM signaling through the diode is demonstrated.
An optical diode consisting of cascaded silicon micro-resonators enables non-reciprocal transmission through direction dependent resonance shift. One-way 10Gbps data transmission is realized through the strong dispersion and attenuation associated with a resonant structure.
We report tributary channel data traffic grooming/exchange of pol-muxed DPSK signal based on Kerr-induced nonlinear polarization rotation. 8 tributary channel data grooming between two pol-muxed 80-Gbit/s DPSK channels is demonstrated with a penalty of <4 dB.
We experimentally demonstrate simultaneous two-channel wavelength conversion of 40-Gbit/s RZ-DPSK WDM signals using four-wave mixing (FWM) in a highly nonlinear fiber (HNLF) without additional pumps. A power penalty of <1 dB is observed as channel spacing varies from 200 GHz to 1 THz.
Ultrawideband (UWB) is defined by the Federal Communications Commission (FCC) for short-range high-capacity wireless communications. We propose and numerically demonstrate a novel scheme of all-optical UWB pulse generation based on parametric processes in cascaded periodically poled lithium niobate (PPLN) waveguides. The commonly used UWB pulses known as derivatives of the Gaussian pulse are considered...
