在热氧化硅衬底上实现了Al（2）O（3）：Er（3+）沟道波导环形激光器。在一个简单的设计中实现了高泵浦功率耦合到环中和低激光输出功率耦合从环。输出功率高达9.5 microW和斜率效率高达0.11%的测量，同时观察到激射的阈值二极管泵浦功率低至6.4 mW的环形激光器的腔长从2.0到5.5厘米。在1530-1557 nm范围内的波长选择通过改变从环的输出耦合器的长度来证明。
Integrated Al(2)O(3):Er(3+) channel waveguide ring lasers were realized on thermally oxidized silicon substrates. High pump power coupling into and low laser output power coupling from the ring is achieved in a straightforward design. Output powers of up to 9.5 microW and slope efficiencies of up to 0.11% were measured while lasing was observed for a threshold diode-pump power as low as 6.4 mW for ring lasers with cavity lengths varying from 2.0 to 5.5 cm. Wavelength selection in the range 1530-1557 nm was demonstrated by varying the length of the output coupler from the ring.
