Figure 8
Measured reflection spectral response of the coated fiber-mirror cavity. The response using the presented 3D micromirror is shown in (a) with a free spectral range of approximately 26 nm; a corresponding line width of 0.45 nm could be obtained as calculated in (b). The response using a flat micromirror is shown in (c); the corresponding line width is approximately 6 nm as shown in (d). The 3D micromirror enhanced the quality factor by more than one order of magnitude. 3D, three-dimensional.
