Patent number: 11715926Abstract: A bidirectional mode-locked fiber laser includes first and second passive optical fibers, a doped optical fiber, first and second polarization controllers, and first and second polarized beamsplitters that are arranged as a ring cavity with clockwise (CW) and counter-clockwise (CCW) directions. The laser imparts different nonlinear phase shifts in the CW and CCW directions, corresponding to CW and CCW repetition rates that are slightly different. When the normalized difference in repetition rates is less than approximately 10?5, both directions can be mode-locked simultaneously, thereby preventing one direction from inhibiting mode-locking of the other direction. Optical-fiber nonlinearity implements an intra-cavity bidirectional artificial saturable absorber based on nonlinear polarization rotation. The laser uses only components with normal group-velocity dispersion (GVD), thereby achieving higher pulse energies than mode-locked lasers utilizing negative GVD.Type: GrantFiled: January 29, 2021Date of Patent: August 1, 2023Assignee: The Regents of the University of Colorado, a body corporateInventors: Shu-Wei Huang, Li Bowen

Patent number: 11105979Abstract: Based on graphene heterostructure in chip-scale silicon nitride microresonators, optoelectronic control and modulation in frequency combs via group velocity dispersion modulation can be demonstrated. By tuning graphene Fermi level from 0.50 eV to 0.65 eV via electric-field gating, deterministic in-cavity group velocity dispersion control from anomalous (?62 fs2/mm) to normal (+9 fs2/mm) can be achieved with Q factor remaining high at 106. Consequently, both the primary comb lines and the full comb spectra can be controllable dynamically with the on/off switching of the Cherenkov radiation, the tuning of the primary comb lines from 2.3 THz to 7.2 THz, and the comb span control from zero comb lines to ˜781 phase-locked comb lines, directly via the DC voltage.Type: GrantFiled: August 30, 2018Date of Patent: August 31, 2021Assignee: The Regents of the University of CaliforniaInventors: Baicheng Yao, Shu-Wei Huang, Chee Wei Wong, Abhinav Kumar Vinod

Patent number: 11063402Abstract: Methods and apparatus for providing dispersion-managed dissipative Kerr solitons on-chip are provided. Microresonators are also provided for producing such solitons. The solitons may be enabled by real-time dynamical measurements on frequency combs. Methods are further provided to determine the temporal structure of the intracavity field in both the fast time axis, with ultrafast time-lens magnifiers at 600 fs timing resolutions, and the slow time axis via optical sampling with a synchronized fiber frequency comb reference. An order-of-magnitude enlarged stability zone of the dispersion-managed dissipative Kerr solitons is achieved versus the static regimes.Type: GrantFiled: October 31, 2017Date of Patent: July 13, 2021Assignee: The Regents of the University of CaliforniaInventors: Chee Wei Wong, Shu-Wei Huang, Yongnan Li
