Gain Evaluation of Optical Designing on Er3+/Yb3+ Co-doped Aluminum Germanate Glass Channel Waveguide
Three types of planar waveguides with S-,U- and F-bend waveguide structures have been designed based on Er3+/Yb3+ co-doped aluminum germanate glass substrates of 6×8 cm2.The beam propagation method (BPM) was employed to simulate the designed waveguides,and the efficient internal gains were obtained in the wavelength range of 1 528~1 559 nm.The maximum internal gains were derived to be 7.27,14.06 and 22.55 dB for S-,U- and F-bend waveguides,which were 0.85,7.64 and 16.13 dB higher than the value of straight one (6.42 dB),respectively.These results indicate that the reasonable designing of the waveguide configurations brings perspective in obtaining higher gain on smaller size waveguide substrate.
