Delay of light in an optical bottle resonator with nanoscale radius variation: dispersionless, broadband, and low-loss
M. Sumetsky
Abstrak
It is shown theoretically that an optical bottle resonator with a nanoscale radius variation can perform a multi-nanosecond long dispersionless delay of light in a nanometer-order bandwidth with minimal losses. Experimentally, a 3 mm long resonator with a 2.8 nm deep semi-parabolic radius variation is fabricated from a 19 micron radius silica fiber with a sub-angstrom precision. In excellent agreement with theory, the resonator exhibits the impedance-matched 2.58 ns (3 bytes) delay of 100 ps pulses with 0.44 dB/ns intrinsic loss. This is a miniature slow light delay line with the record large delay time, record small transmission loss, dispersion, and effective speed of light.
