Electro‐optic Polymer Ring Resonator Modulator on a Flat Silicon‐on‐Insulator

Abstract: Optical polymers are a promising material of choice in the development of hybrid silicon photonics devices. Particularly, recent progress in electro‐optic (EO) active polymers has shown a strong Pockels effect. A ring resonator modulator is a vital building block for practical applications, such as signal processing, routing, and monitoring. However, the properties of the hybrid silicon and EO polymer ring modulators are still far from their theoretical limits. Here, we demonstrate a unique design of a hybrid … Show more

“…It is worth noting that the response time scale of the nonlinear effect of EO polymer is in the femtoseconds range so that it can be ignored . Thus, the frequency limitation is typically determined by two factors, cavity lifetime and the RC constant. , For the cavity lifetime, it is determined by the calculated Q factor (about 203), which equates to a bandwidth of 1.14 THz. Therefore, the electro-optic bandwidth of the device is mainly constrained by the RC time constant ( f 3 dB = 1/2πRC).…”

“…Furthermore, for the lumped EOM device, we also evaluate the theoretical 3-dB bandwidth f 3dB of the metafiber EOM. f 3dB can be calculated using the equation: (1/f 3dB ) 2 = (2πτ) 2 + (2πRC) 2 , where τ is the photon lifetime, R and C are the resistance and capacitance of the device system, respectively 55 . The plasmonic-organic hybrid structure can be regarded as a parallel-plate capacitor, as depicted in the left of Fig.…”

“…Moreover, their wavelength selectivity enables dense wavelength division multiplexed links at the micrometer scale and consequently increases aggregate link bandwidth drastically. [8][9][10] Up until now, ring modulators have been realized by using a number of material platforms, such as silicon (Si), EO polymer, and crystals. [11][12][13] Recent progress of Si modulators relying on the free-carrier plasma-effect is of interest and offers a realistic means of achieving ultra-fast data transfer, enabled by a careful balance among the doping configuration, loss control, and free-carriers' lifetime.…”
