We present a new adaptive-optics technique for the optimization of photon collection from a simulated ion. Our technique uses a genetic algorithm to correct wavefront aberrations via deformable mirror before coupling into a single-mode fiber.
Based on the three-fiber-optic grid interferogram technique, a shape sensing approach has been proposed and demonstrated in this paper. The square and hexagon grid interferometric fringe pattern formed by the fiber-optic interferometric grid generator has been designed and performed. The designing and realizing methods of the fiber-optic interferometric grid pattern by using three PM fibers are discussed...
In conventional optical data transmission schemes, electrical filters and/or optical filters are used to improve the quality of system performance. In this paper, improved design of dense wavelength division multiplexing (DWDM) optical systems is achieved by using a selective electrical filter assignment method. The methodology objective is to optimize system design and mitigate the effects of fiber...
Optical communication systems based on dense wavelength division multiplexing (DWDM) would benefit from the ability to adjust the operating wavelength of a laser transmitter. Previous attempts, including thermal adjustment, etalon based wavelength locking, and various types of optical frequency and phase locked loops such as the Pound-Drever-Hall technique suffer from weaknesses including sensitivity...
