英文摘要 We have proposed and set up theoretical models for analyzing all-solid photonic bandgap fibers and gratings. Some phenomenon found in our experiment are analyzed and explained based on these models.The theoretical results agree well with the experimental results. The fabrication technology of Bragg and long-period gratings written on all-solid photonic bandgap fibers have been in hand. The multi-core coupling and dispersion characteristics have been deeply investigated and some novel all-solid photonic bandgap fibers have been proposed and demonstrated.The fiber Bragg and long-period gratings written in different bandgaps of all-solid photinic bandgap fibers have been first reported and their sensing characteristics have been investigated.Some unique coupling phenomenon between core mode and guided and radiative cladding Bloch modes have been observed and theoretical explained, which interpretated the transmission mechanism of the photonic bandgap fiber.High order resonances between fundamental core mode and cladding LP01 supermodes are demonstrated in long period fiber gratings inscribed in all-solid photonic bandgap fibers. The resonance wavelengths of the long period garings calculated by way of photonic bandgap theory agree with the experimental results.the mechanism of grating formation has been researched deeply through coupled-mode theory and the cutback experiments. Moreover,a variety of temperature-control and electric-control tunable solid-core photonic bandgap fiber and based devices, such as filters and based sensors, have been proposed and demonstrated. We published 26 papers including 18 SCI index papers (8 papers have been publised in Opt. Lett. and Opt. Express)and 3 invited papers at international conferences.These articles have been cited 35 times or more. We have applied 2 invetion patents. 3 PhD and 7 Master students have graduated supported by this project.
