| Abstract: | A fiber optical isolator with a spherical magneto optical crystal was developed in this paper. The insertion loss, isolation and return loss of a experimental structure with a YIG sphere for this device were measured to be less than 8.9dB, greater than 28dB and 45dB, respectively. According to analysis the lowest insertion loss and the effetive lenght of this isolator could be droped down to 1dB and 0.5mm, respectively. |
