“…However, the required electrical power and the number of I/O lines ultimately limit integration density. Passive thermo-optic compensation of silica photonic devices by a negative thermo-optic polymer cladding (PMMA) was first reported by Kokubun et al [2][3][4]. Lee et al [5,6] have extended the application of compensating polymer claddings to silicon ring resonators and have exhibited significant thermo-optic compensation to a TDWS of 2pm/K.…”

Abstract:We report the design criteria and performance of Si ring resonators for passive athermal applications in wavelength division multiplexing (WDM). The waveguide design rules address i) positivenegative thermo-optic (TO) composite structures, ii) resonant wavelength dependent geometry to achieve constant confinement factor ( Γ ), and iii) observation of small residual second order effects. We develop exact design requirements for a temperature dependent resonant wavelength shift (TDWS) of 0 pm/K and present prototype TDWS performance of 0.5pm/K. We evaluate the materials selection tradeoffs between high-index contrast (HIC) and low-index contrast (LIC) systems and show, remarkably, that FSR and footprint become comparable under the constraint of athermal design.

“…An analysis of the principle of athermalisation had been carried out in other studies, which showed that negative dn/dT was required to counter the effect of thermal expansion of the glasses, in order to achieve athermalisation [14][15][16][17][18]. To our knowledge, this work represents the first reported data of dn/dT for sodium borophosphate glasses.…”

“…Polymers were recently investigated also as a cladding material to fabricate passive athermal optical filters [134]. This idea was demonstrated for the first time nearly twenty years ago [135]. In this case the polymer is used as top cladding and its thermooptic coefficient has to counterbalance the one of the underlying (silicon) waveguide.…”

In this review materials and technologies of the hybrid approach to integrated photonics (IP) are addressed. IP is nowadays a mature technology and is the most promising candidate to overcome the main limitations that electronics is facing due to the extreme level of integration it has achieved. IP will be based on silicon photonics in order to exploit the CMOS compatibility and the large infrastructures already available for the fabrication of devices. But silicon has severe limits especially concerning the development of active photonics: its low efficiency in photons emission and the limited capability to be used as modulator require finding suitable materials able to fulfill these fundamental tasks. Furthermore there is the need to define standardized processes to render these materials compatible with the CMOS process and to fully exploit their capabilities. This review describes the most promising materials and technological approaches that are either currently implemented or may be used in the coming future to develop next generations of hybrid IP devices.
