【Abstract】 By using the local mode coupled theory, the transmission properties of two kinds of optical fiber taper probes, the etched taper and the pulled taper, is analyzed and compared. The coupling efficiency distribution along the probe taper and the transmission efficiencies versus the taper length, the tip diameter and the wavelength are given.更多还原
