A MEMS tunable capacitor with angular vertical comb-drive (AVC) actuators is described where high capacitances and a wide continuous tuning range is achieved in a compact space. The comb fingers rotate through a small vertical angle which allows a wider tuning range than in conventional lateral comb drive devices. Fabrication of the device is straightforward, and involves a single deep reactive ion etching step followed by release and out-of-plane assembly of the angular combs.

A fiber-delivered probe suitable for CARS imaging of thick tissues is practical. The disclosed design is based on two advances. First, a major problem in CARS probe design is the presence of a very strong anti-Stokes component in silica delivery fibers generated through a FWM process. Without proper spectral filtering, this component affects the CARS image from the tissue sample. The illustrated embodiments of the invention efficiently suppress this spurious anti-Stokes component through the use of a separate fiber for excitation delivery and for signal detection, which allows the incorporation of dichroic optics for anti-Stokes rejection. Second, the detection of backscattered CARS radiation from the sample is optimized by using a large core multi mode fiber in the detection channel. This scheme produces high quality CARS images free of detector aperture effects. Miniaturization of this fiber-delivered probe results in a practical handheld probe for clinical CARS imaging.
