Whispering gallery mode excitation and collection using fused-tapered fiber tips
In this paper, we investigated whispering gallery mode (WGM) coupling in fused silica microspheres using fused-tapered fiber tips (FTFT). FTFT couplers are fabricated from single mode fibers using a standard splicing machine. FDTD simulation is first performed to demonstrate the feasibility of FTFT...

In this paper, we investigated whispering gallery mode (WGM) coupling in fused silica microspheres using fused-tapered fiber tips (FTFT).

We obtained the comb-like eigenfrequency spectrum from both schemes. The measured free spectrum range (FSR) is around 2nm and the Q-factor is in the order of 105. |
