1. A photonic apparatus, comprising:

  • an interferometer having a second arm, wherein the interferometer is characterized by a negative net optical path length change as a function of temperature, δ

    LM

    T; and

    a waveguide closed loop resonator characterized by a positive optical path length change as a function of temperature, δ

    LR

    T, disposed in light-coupling proximity to the second interferometer arm, wherein the absolute value of δ

    LM

    T is equal to the absolute value of δ

    LR

    T, such that the apparatus is characterized by a resonance having substantially no spectral shift as a function of temperature, wherein the apparatus is an athermal/temperature insensitive, resonant photonic device.
