Abstract
We propose and experimentally demonstrate an on-chip all-optical
silicon photonic crystal nanobeam cavity (PCNBC) modulator. With the
advantages of the strong two-photon absorption (TPA)-induced
thermo-optic (TO) effect, ultrahigh thermal-efficient tuning with
π phase shift temperature difference
ΔTπ of 0.77°C and power
Pπ of 0.26 mW is implemented.
Moreover, the all-optical modulation is carried out by a pulsed pump
light with an average switching power of 0.11 mW. The response times
for the rising and falling edges are 7.6 µs and 7.4 µs, respectively.
Such a thermal-efficient modulator is poised to be the enabling device
for large-scale integration optical signal control systems.
