However, the relatively large optical constants change between different states of calls for a set of new design rationales. Here we report a non-perturbative design that enables low-loss device operation beyond the traditional figure-of-merit limit. The basic design rationale is to engineer the light propagation path through the OPCMs when it is in the low-loss amorphous state, and divert light away from the lossy crystalline state leveraging the large mode modification induced by the O-PCM phase transition. Following this approach, we demonstrate broadband photonic switches with significantly enhanced performances compared to current state-of-the-art.","PeriodicalId":363843,"journal":{"name":"Active Photonic Platforms XI","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134404621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanometer-scale thin films and atomic layers derived from the layered bulk of h-BN crystals have been widely adopted for enabling new two-dimensional (2D) devices and systems, thanks to its excellent dielectric, optical, mechanical, and thermal properties. Lately, h-BN thin layers have also emerged as an attractive material and device platform for nanoscale optics, photonics, and quantum engineering. In this proceedings paper, we report on some of our studies and initial results toward developing integrated photonic circuitry based on this van der Waals (vdW) layered crystal. The first part summarizes our effort on the creation and optical characterization of defect-related quantum emission in exfoliated and dry-transferred h-BN flakes. Based on the statistics from our measurements and state-of-the-art knowledge in the field, we have identified a group of emitters with emission wavelength around 710 nm exhibiting large Debye-Waller (DW) factor. We then describe optical waveguide and cavity designs at the wavelength range of interest, with the aim of achieving high optical cooperativity. Combined with our studies in ultrathin h-BN crystalline nanomechanical resonators and phononic waveguides, these new explorations in quantum emitters will help pave the way to facilitating h-BN photonic devices and integrated systems for both classical and quantum applications.","PeriodicalId":363843,"journal":{"name":"Active Photonic Platforms XI","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122958144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The radiative recombination lifetime has been studied at 7K from time-resolved photoluminescence (TRPL) experiments at a certain excitation power. The optimal combination of pitch (separation between NPs) and diameter in the growth process of this nanostructure has also been measured.

Here we show that antenna made out of hexagonal boron nitride (hBN) possesses different resonances enabled by the supporting high-k modes and their reflection from the antenna boundaries. Multipole resonances cause the decrease in the reflection from antenna array to zero, which can be ascribed to resonant Kerker effect satisfying generalized zero back-scattering condition for particles in the array. Reflection and transmission through the van der Waals heterostructure with hBN antennas array can be tailored and actively switched by tuning optical properties of two-dimensional materials. Transdimensional photonic lattices consisting of resonant hBN antennas in the engineered periodic arrays have great potential to serve as functional elements in ultra-thin optical components and photonic devices.","PeriodicalId":363843,"journal":{"name":"Active Photonic Platforms XI","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130085262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drawbacks of these methods are the volatile nature and the extremely small change in the complex refractive index (Δn<0.01). In order to achieve low energy consumption and smaller footprint for applications such as photonic memories or computing, it is essential that the two optical states of the system exhibit high optical contrast and remain non-volatile. Phase change materials such as GST provide a solution in that it exhibits drastic contrast in refractive index between the two non-volatile crystallographic states which can be switched reversibly. Here, we first show that GST can be integrated with a Si ring resonator to demonstrate a quasi-continuous optical switch with extinction ratio as high as 33dB. Secondly, we demonstrated GST-integrated 1×2 and 2×2 Si photonic switches using a three-waveguide coupler design which exhibits a low insertion loss of ~1dB and a compact coupling length of ~30μm. The crosstalk is as small as -10dB over a bandwidth of 30nm.","PeriodicalId":363843,"journal":{"name":"Active Photonic Platforms XI","volume":"753 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116113158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
