Abstract

The composition and operating principle of the 980 nm LD-FBG multiple optical cavity subassembly are introduced

its spectrum test results under different driving currents and ambient temperatures reported and the effects of the reflectivity of the wedge-shaped coupled fiber on its spectrum

the wavelength locking and the optimization of its structure analyzed and discussed.The test results indicate that the peak value of the optimized subassembly changes by

0.6 nm and the SMSR is

45 dB under the optical power of 100

50 mW and at the ambient temperature of 25

5 ℃.
