1. A miniaturized integrated frequency locked optical whispering evanescent resonator, comprising:
an optical source;
an optical path having a first end and a second end, said optical path arranged to be optically coupled to said optical source at said first end;
an optical resonator disposed proximate said optical path along a side of said optical path between said first and second ends, said optical resonator having an optical whispering-gallery mode and being optically coupled to said optical path through an evanescent field to excite said optical whispering-gallery mode;
an optical receiver arranged to be optically coupled to said second end of said optical path; and
a digital data processor configured to communicate with said optical receiver and said optical source,
wherein said digital data processor comprises a frequency locking system and a data acquisition system configured thereon,
wherein said frequency locking system controls a frequency of said optical source to be tuned to said optical whispering-gallery mode of said optical resonator, and
wherein the frequency locking system and the data acquisition system are implemented in a miniature sized single-board computer such that said miniaturized integrated frequency locked optical whispering evanescent resonator weighs less than 15 kg and is containable within a volume less than 30 liters.
