Representative semiconductor materials fabricating NW lasers are ZnO, GaN and Cad's, etc. Such NW lasers are currently among the smallest known lasing devices, with lengths between one and several tens micrometers and diameter that can be significantly smaller than the emission wavelength in vacuum. For a single-crystalline NW, the end facets form natural mirror surface that create an axial resonator. That is, one-dimensional semiconductor NWs not only act as a gain medium but also a waveguide and a Fabry-Pérot resonator, which provide coherent feedback. The light-emitting capability of the NWs, combined with their other unique features that arise due to their one dimensionality, make them particularly interesting to consider as a candidates for components of future nanoscale photonic systems. However, most advances of NW lasers were successfully realized via wide-bandgap semiconductor materials, giving an ultraviolet or blue laser emission, and little investigation of NW lasers in near-infrared spectral range was reported. Here we describe the growth of GaAs-based NWs using selective-area metalorganic vapor phase epitaxy (SA-MOVPE) and their near-infrared lasing at 810–820 nm wavelengths, inside GaAs/GaAsP core-shell NWs.","PeriodicalId":367324,"journal":{"name":"2010 IEEE Photonics Society Winter Topicals Meeting Series (WTM)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121363615","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}

Utilising a novel probe-based fluorescence confocal endomicroscopy (FCE) approach, we have 1) established the most appropriate exogenous contrast agent for use in this setting, 2) demonstrated that cell attrition and morphological changes caused by platinum-based chemotherapy treatment can be tracked via this technique, 3) characterised the morphological differences between normal and cancerous ovarian epithelium, and 4) shown that the FCE imaging system can detect 5-aminolevulinic acid-induced protoporphyrin IX (PpIX) autofluorescence from in vitro ovarian cancer cell lines and ex vivo small cell lung cancer tissue.

Being the dominant light interaction process, scattering prevents tissue from being transparent. Although the spectral properties [1] and angular profiles [2] of scattered light can reveal useful physiological information about a given tissue sample, scattered light is generally regarded as poor in imaging information. This is due to the severe deterioration of the incident light field, caused by disordered amplitude and phase modulation of its wavefront as it propagates through the tissue. Yet, it is also known that elastic optical scattering is a deterministic and time reversible process. In other words, if we can record the phase and amplitude of the propagating scattered light field completely and reproduce a back propagating optical phase conjugate (OPC) field or a time‐ reversed light field this field should be able to retrace its trajectory through the scattering medium and return the original input light field.","PeriodicalId":367324,"journal":{"name":"2010 IEEE Photonics Society Winter Topicals Meeting Series (WTM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127133388","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}
