硅光子学通过利用来自微电子工业的高度发达的制造工艺来实现大规模光电集成。然而，虽然已经在硅平台上展示了丰富的器件组合，但片上光源仍然是一个关键挑战，因为材料的间接带隙抑制了有效的光子发射，从而阻碍了激光发射。在这里，我们展示了一类红外激光器，可以在绝缘体上硅（SOI）集成平台上制造。该激光器基于硅有机混合（SOH）集成概念，并将联合收割机纳米光子SOI波导与提供光学增益的染料掺杂有机包覆材料相结合。我们展示了脉冲室温激光与片上峰值输出功率高达1.1 W，在1,310 nm的波长。SOH方法使得能够有效地大规模生产在近红外中发射的硅光子光源，并且提供了通过适当选择染料材料和谐振器几何形状在宽范围内调谐发射波长的可能性。 用于硅光子电路的片上光源仍然是一个挑战，因为硅的间接带隙阻止了有效的光发射。作者证明，激光可以通过将标准绝缘体上硅波导与染料掺杂的有机包层材料相结合来实现，以提供光学增益。
Silicon photonics enables large-scale photonic–electronic integration by leveraging highly developed fabrication processes from the microelectronics industry. However, while a rich portfolio of devices has already been demonstrated on the silicon platform, on-chip light sources still remain a key challenge since the indirect bandgap of the material inhibits efficient photon emission and thus impedes lasing. Here we demonstrate a class of infrared lasers that can be fabricated on the silicon-on-insulator (SOI) integration platform. The lasers are based on the silicon–organic hybrid (SOH) integration concept and combine nanophotonic SOI waveguides with dye-doped organic cladding materials that provide optical gain. We demonstrate pulsed room-temperature lasing with on-chip peak output powers of up to 1.1 W at a wavelength of 1,310 nm. The SOH approach enables efficient mass-production of silicon photonic light sources emitting in the near infrared and offers the possibility of tuning the emission wavelength over a wide range by proper choice of dye materials and resonator geometry. On-chip light sources for silicon photonic circuits remain a challenge since the indirect bandgap of silicon prevents efficient light emission. The authors demonstrate that lasing can be achieved by combining standard silicon-on-insulator waveguides with dye-doped organic cladding materials to provide optical gain.
