Claim 0:
1. A photonic system comprising:
a waveguide;
a micro ring modulator (MRM) spaced from the waveguide;
a heater configured to increase a temperature of the MRM, wherein the heater comprises:
at least one first doped region, wherein each first doped region of the at least one first doped region has a first dopant type; and
at least one second doped region, wherein each second doped region of the at least one second doped region has a second dopant type opposite the first dopant type; and

a cooling element configured to decrease a temperature of the MRM, wherein the cooling element comprises:
a plurality of third doped regions, wherein each third doped region of the plurality of third doped regions has the first dopant type; and
a plurality of fourth doped regions, wherein each fourth doped region of the plurality of fourth doped regions has the second dopant type.
