使用低重复率范围内的飞秒脉冲在掺铒氟硅酸盐玻璃样品内制造通道波导。使用多重扫描制造技术来控制波导横截面。当与康宁 SMF-28 光纤耦合时，1.85 厘米长的波导表现出 4.3 dB 的总背景插入损耗。在最大可用泵浦功率下，该器件在 1537 nm 处表现出 1.7 dB 的内部增益。
A channel waveguide is fabricated inside an erbium-doped oxyfluoride silicate glass sample using femtosecond pulses in the low repetition rate regime. The waveguide cross section is controlled using the multiscan fabrication technique. The 1.85-cm-long waveguide exhibits a total background insertion loss of 4.3 dB when coupled to Corning SMF-28 fibers. Under the maximum available pump power, the device exhibits an internal gain of 1.7 dB at 1537 nm.
