Abstract: A divided pulse nonlinear optical source may be generated by combining nonlinear wave generation techniques with pulse division that can divide a parent pulse into N divided pulses, each divided pulse separate temporally. The N divided pulses can be passed into a nonlinear optical medium to generate an output. The output can include at least one output pulse for each divided pulse. The center wavelengths of each output pulse can be tuned so that each may have a center wavelength that is the same as, or differs from, each other output pulse. In some embodiments, the output pulses may be combined to generate the output. The output can be power scalable and wavelength tunable.

Abstract: A biocompatible and biodegradable polymeric step-index optical fiber includes a core and a cladding around the core. The core is made from a core material fabricated by bonding a citric acid and at least a first monomer using a synthesis process. The cladding is made from a cladding material fabricated by bonding the citric acid and at least a second monomer using the synthesis process. The core has a refractive index higher than that of the cladding, while a difference between an initial modulus of the core and the cladding is preferably less than 30% and a difference between the biodegradation rates of the core and cladding is preferably less than 30% after about 4 weeks. Optical properties of the core and cladding are tunable by adjusting monomer ratios, choices of monomers or cross-linking degrees.
