Research output: Contribution to journalArticlepeer-review


The authors report the design, fabrication, and study of a fully monolithic solid-state amplifier based on a neodymium doped sol-gel tapered rib waveguide with a thin guiding layer of 360 nm. Signal (1064 nm) and pump (803 nm) light were coupled into and out of the amplifier by grating couplers. A gain of 4.8 dB (3.75 dB net internal gain) was obtained from a 1 cm long device.
