Study on Polarization Properties of Whispering Gallery Mode Fiber Laser
The polarization properties of whispering gallery mode (WGM) fiber laser pumped by evanescent waves are studied. Both transverse electric (TE) wave and transverse magnetic (TM) wave exist on condition that pump beams transmit in a bared optical fiber in skew way, additionally for the same number of radial mode order and angular mode number, the wavelength difference between TE and TM waves monotonely increases with fiber diameter decreasing, and monotonely decreases with the refractive index of cladding solution increasing. The observed experimental results, on the basis of excitation mechanics of evanescent wave pumped WGM fiber laser in combination with the analytic asymptotic formula, validate the theoretical value very well.
