“…In terms of low-power-consumption operation, vertical-cavity surface-emitting lasers (VCSELs) [8]- [11], micro-disk lasers [12], [13], and photonic crystal lasers [14]- [17] were reported. Although VCSELs are suitable for low power consumption with sufficient light output power, 45°-tilted micro-mirrors are required for in-plane integration [18]. While micro-disk lasers and photonic crystal lasers are very attractive for ultra-low threshold current operation due to their strong optical confinement effect into a very small active region, very strong optical confinement leads to lower optical output power.…”

To advance on-chip optical interconnections, membrane distributed-reflector (DR) lasers with low threshold current and high-efficiency operation at one side output were realized. First, a membrane distributed Bragg reflector (DBR) laser with 80-µm-long active section and 50-µm-long DBR section was fabricated to clarify the DBR reflectivity. An external differential quantum efficiency of 35% for the output from the front facet was obtained, and the DBR reflectivity was estimated to be 75%. Next, a membrane DR laser with 61-µm-long distributed feedback section and 50-µm-long DBR section was fabricated. A threshold current of 0.48 mA, external differential quantum efficiency from the front side waveguide of 26%, and light output ratio from the front to the rear sides of 13 were obtained. The lasing spectrum showed a single-mode operation with a side-mode suppression-ratio (SMSR) of 40 dB. Finally, small-signal direct modulation was carried out and a modulation current efficiency factor of 7.9 GHz/mA 1/2 and 7 GHz/mA 1/2 were, respectively, obtained for the 30-µm-long and 61-µm-long devices.

“…As for optical interconnects systems, polymer waveguides also give a promising performance as chip-level optical interconnects on a silicon platform [106]. High data transmission rate as 10 Gbit s −1 and low bit error rates better than 10 −12 in polymer waveguide-based optical interconnects exhibit the applicability in high-speed data transmission [107]. In terms of glass waveguide, various advantages can be found in glass materials such as low cost of material, being compatible with optical fibers, low propagation loss, birefringence, high stability and reliability [108].…”

Two-dimensional(2D) materials have received extensive attention in optoelectronics because of their unique characteristics. However, due to the extremely thin thickness of 2D materials, their optical absorption is limited. In recent years, researchers have used different effects and structures to enhance the optical absorption of 2D materials. Waveguide, as a device to guide and limit light propagation, has been integrated into photodetectors based on 2D materials, and most of them are applied in the infrared spectrum. This article reviews the development of waveguide-integrated photodetectors based on 2D materials, mainly in the infrared spectrum in recent years. Discussions mainly focus on the preparation of materials in waveguide-integrated photodetectors, the design and simulation of waveguide structures, and the research results and applications of waveguide-integrated photodetectors in recent years are summarized. Finally, the challenges and prospects of waveguide-integrated photodetectors are put forward and discussed.
