New record: 3D-printed optical-electronic integration

13.06.2019

Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information processing, paving the way for the next-generation integrated circuits (ICs).

The ever-increasing demand on bandwidth and information density in ICs call for the micro/nano functional devices capable of being fabricated in three-dimensional (3D) ICs, which is desirable for their improved performance in data processing under lower consumption.


Schematic illustration of an integrated electrically controlled microlaser module for optoelectronic hybrid integration. Briefly, this module is designed to be a thermo-responsive polymer resonator on top of a chip-scale metal heating circuit. The voltage is applied in-plane with the current transport to provide local-area thermal field, which induces the lasing wavelength change of the upper dye-doped microresonators.

In such highly integrated circuits, however, selective electrical modulation of specific micro/nanoscale optical devices, including light sources and waveguides, is a key requirement for yielding more functional and more compact integrated elements, but hindered by the normal used nonlinearity found in electro-optic materials.

Femtosecond laser direct writing (FsLDW), as one of the 3D printing techniques, enables the direct and addressable construction of 3D-integrated optoelectronic devices utilizing organic compounds with two-photon polymerized features.

With doping flexibility, the polymerized microstructures can be readily incorporated with organic dye molecules to produce functional devices, like coherent laser sources. Besides, organic polymers possess excellent responsiveness to external stimuli, including temperature.

Their large thermo-optic coefficient enables the realization of the electrical tuning of resonant wavelength with high efficiency when they are fabricated into microcavity structures.

The incorporation of thermo-responsive polymeric microlaser with underneath electrical microheater in the 3D fabrication manner can be used as an effective hybrid microlaser module with selective electric modulation towards optical-electronic integration.

Very recently, Professor Yong Sheng Zhao's group in the Institute of Chemistry, Chinese Academy of Sciences demonstrated an in situ electrically modulated microlaser module based on 3D-printed dye-doped polymeric microdisks, which is published in Science China Chemistry.

The thermo-optic effect of the polymer matrix enabled the tuning of lasing modes from the microdisk upon heating. The shape designability of FsLDW allows the fabrication of higher-level microstructures to manipulate light signals, including the waveguide coupled microdisks for light remote control and the coupled double-microdisk resonators for laser mode selection. The latter microstructure was further integrated with an underneath electrical microheater.

As a result, the cavity resonant wavelength can be shifted on the basis of resistance heating controlled optical length change through the thermo-optic effect of polymeric matrix material, which enabled an electrical modulation of the output wavelength of the 3D-printed microlaser module.
