    • An optical device includes a light source (102), an optical microresonator (118) that supports at least a first optical guided mode (128) propagating along a first direction and at least a second optical guided mode (164) propagating along a second direction different from the first direction, and a detector (110,114). At least the first optical guided mode is excited by the emitted broadband light without the second optical guided mode being excited by the emitted broadband light. In some embodiments The detector receives and wavelength-averages light from the at least a second optical guided mode of the optical microresonator. In some embodiments, at least one of the light source, the microresonator and the detector is tunable.

    • The field of the invention generally relates to a shellac-based enteric coating with a reliable and consistent dissolution profile in both acid and neutral environments based on the selective choice of coating excipients used with the shellac. The enteric coating formulation includes a shellac, a maltrin, sodium alginate, one or more plasticizers, and optionally talc. The shellac is present in a range of approximately 40% to 60% w/w % and has an acid number of between 71 and 73. The maltrin is present in a range of approximately 15% to 30% w/w %. The sodium alginate is present in a range of approximately 15% to 30% w/w %. The one or more plasticizers are present in a range of approximately 2% to 20% w/w %. The optional talc is present in a range of 0% to 10%.

    • An optical sensing system and method is disclosed. In one embodiment, a method of detecting a scattering center includes the step of providing an optical sensing system including a light source, one or more bus waveguides where a first bus waveguide has an input port that is in optical communication with the light source, a microresonator optically coupled to the one or more bus waveguides, and a scattering center which is capable of optically coupling to the microresonator. The method further includes the steps of exciting at least a first resonant guided optical mode of the microresonator with the light source, altering a strength of optical coupling between the scattering center and the microresonator to induce a change in optical scattering between the first mode and at least a second guided optical mode of the microresonator, and detecting a change in transfer of energy from the first mode to the second mode.
