Their small size, high-gain, and ability to be turned on and off fast offer interesting possibilities for photonic switches. We have used a design to implement polarization insensitivity. Quantum wells of alternative compressive and tensile direction of strained are stacked up in the active region. Compressively strained layers provide TE gain through electron-heavy hole recombinations, while tensile strained wells provide predominantly TM gain through electron to light hole recombinations. Amplifiers can be fabricated at both 1.3 and 1.5 /spl mu/m wavelength.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123920648","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}

Photocurrent spectroscopy, belonging to the traditional methods of semiconductor physics, gained an entirely new range of application by employing an optical near-field microscope as the optical excitation source. Thus near-field optical beam induced current (NOBIC) spectroscopy has been developed. It combines the spatial resolution of less than some 100 nm of electron beam based techniques such as electron beam induced current (EBIC) with the advantages of providing selective excitation of the laser structure if a tunable wavelength excitation source is used and being completely non-destructive. Here, a NOBIC study of different GaAs-AlGaAs high power diode laser array structures such as double quantum well (DQW) graded index separate confinement heterostructures as well as step index AlGaAs structures is presented.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122429583","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}

Strides toward future development of particle measurement instrumentation aim to reduce cost and device size, thus making laser diodes a favorable choice. Laser diodes, however, exhibit several characteristic properties which must be addressed in order to achieve stable operation. We have devised and tested a simple cost efficient technique to ensure accurate particle measurement without the cost or bulk associated with laser stability instrumentation. We have investigated the power stability of a laser diode pumped external resonant cavity optical setup. We propose that the described system can be used for particle measurement applications by using the detected cavity output power as a trigger signal for a second detector, used to measure scattered light from particles pumped through the laser beam.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127134721","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}

Optically preamplified receivers circumvent the gain-bandwidth limitation of APD receivers and have demonstrated improved receiver sensitivity in optical fiber systems at data rates up to 10 Gbit/s. In order to obtain maximum sensitivity, an optically preamplified receiver must be optical amplifier noise limited rather than thermal noise limited. Operation in this regime is more difficult to achieve at higher frequencies, however, due to reduced detector quantum efficiency and higher electronic receiver noise. We demonstrate an optically preamplified receiver comprised of a semiconductor optical amplifier (SOA) and 25 GHz Schottky InGaAs photodiode operating at the SOA noise limit. Because of the broadband, low-responsivity of this photodiode, these results apply over its entire spectral range (400-1600 nm), subject to SOA availability, as well as to operation at frequencies up to 120 GHz.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125823407","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}
