“…For instance, recent work on in-situ strain tunable suspended cavities shows the potential that EHDIJ printing could have for integrating a broad range of colloidal emitters into actively tunable photonic devices. [56] Lastly, a significant contribution to the broad line widths of the as-printed QDs is due to the variation among emitters in an aggregate deposition. Seeking out reliable methods for deterministically positioning single QDs is becoming a focus for those interested in functionalizing colloidal emitters for their potential in single-photon manipulation and entanglement.…”

Nanophotonic structures are a foundation for the growing field of light‐based quantum networks and devices enabled by their ability to couple with and manipulate photons. Colloidal quantum dots (QDs) are uniquely suited to complement this range of devices due to their solution‐processability, broad tuneability, and near‐unity photoluminescence quantum yields in some cases. To bridge the gap between them, electrohydrodynamic inkjet (EHDIJ) printing serves as a highly precise and scalable nanomanufacturing method for deterministic positioning and deposition of attoliter‐scale QD droplets. This includes heterointegration in devices that are challenging to create by conventional subtractive semiconductor processing, such as QDs emitters coupled to substrate‐decoupled nanoscale resonant structures. In this work, the first successful application of EHDIJ printing for the integration of these colloidal QDs into suspended nanophotonic cavities is demonstrated, achieving selective single‐cavity deposition for cavity pairs as close as 100 nm apart. These results motivate the development of future suspended hetero‐integrated devices that utilize EHDIJ printing as a sustainable, additive, and scalable method for quantum photonics nanomanufacturing.

“…Strain may also be actively tuned in situ when the monolayer is deposited on top of a piezo-responsive material. [176,177] Ref. [176] showed that single photon emitters in WSe 2 defined along a wrinkle may be tuned in emission energy over a range as wide as 18 meV.…”

In this review, the current landscape of emergent quantum materials for quantum photonic applications is described. The review focuses on three specific solid‐state platforms: single emitters in monolayers of transition metal dichalcogenides (TMDs), defects in hexagonal boron nitride (hBN), and colloidal quantum dots in perovskites (PQDs). These platforms share a unique technological accessibility, enabling the rapid implementation of testbed quantum applications, all while being on the verge of becoming technologically mature enough for a first generation of real‐world quantum applications. The review begins with a comprehensive overview of the current state‐of‐the‐art for relevant single‐photon sources in the solid‐state, introducing the most important performance criteria and experimental characterization techniques along the way. Progress for each of the three novel materials is then benchmarked against more established (yet complex) platforms, highlighting performance, material‐specific advantages, and giving an outlook on quantum applications. This review will thus provide the reader with a snapshot on latest developments in the fast‐paced field of emergent single‐photon sources in the solid‐state, including all the required concepts and experiments relevant to this technology.

We propose and realize a 1D photonic crystal nanocavity laser embedded in a polydimethylsiloxane (PDMS) thin film. The nanolaser in PDMS exhibits a significant optical response to structural deformation. It can be attached to object surfaces or integrated into different configurations, enabling the detection of different quantities that induce strain in the film. In experiments, this nanolaser can detect temperature variations or micrometer-scale bending degrees by attaching it to a temperature-controllable or bendable plate, respectively. Moreover, we further utilize the film as a diaphragm of a chamber to demonstrate its potential as a highly sensitive pressure gauge and chemical sensor. By adjusting the thickness of the PDMS thin film and the position of the nanolaser, we experimentally achieved a minimum detectable gas pressure variation of 0.12 kPa and a sensing dynamic range of 46 dB. We also investigate the optical response of the nanolaser to the swelling of the PDMS thin film induced by different organic solvents in experiments. The experimental wavelength shift rates over time are proportional to different chemical vapors’ PDMS swelling ratios, which can be used to identify specific chemical vapors within the chamber that induce PDMS swelling. Based on the experimental results and the capability of reattaching to different objects or configurations, we believe that our PhC nanolaser demonstrated herein holds significant potential as a highly sensitive mechanical and chemical sensor.
