The current study employed the finite difference time domain method to analyze D-shaped optical fiber.Major parameters tested included the cladding removal depth,the cladding removal length,the re-fractive index of coating and the refractive index of background on the influence of energy in the optical fi-ber.The results showed that changing the structure of the D-shaped optical fiber could control the energy in the fiber.
