The narrow stripe near the middle of the cavity acts as a spatial filter to maintain a good quality spatially coherent output, whilst the wide stripes at the facets have the dual benefits of increasing the active volume (thus increasing optical power generation) and increasing the threshold power before catastrophic facet damage occurs. High power single lateral mode operation has already been demonstrated by using various tapered devices[l, 2, 3] and much work has been carried out on tapered semiconductor laser amplifiers [5, 4]. However, the nature of double tapered device in obtaining high power and diffraction limited output is still poorly understood and optimization in design is badly needed.","PeriodicalId":365685,"journal":{"name":"Semiconductor Lasers Advanced Devices and Applications","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576171","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}

However, if used in a high data transmission rate system, there may be a minimum requisite modulation bandwidth. In addition, signal-to-noise considerations often demand a minimum optical output power. While lowering the threshold current often improves the bandwidth and output power at a given operating current, it is not true that a laser optimized solely for the lowest threshold current will have the lowest operating current when biased to meet the requirements of a particular system. In this talk we discuss how the laser device parameters are optimized to produce the lowest operating current in applications with given bandwidth and optical power requirements.","PeriodicalId":365685,"journal":{"name":"Semiconductor Lasers Advanced Devices and Applications","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127492166","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}

Flared amplifiers and oscillators have been found to be less sensitive to filamentation effects than broad area devices, although filamentation still ultimately limits the performance of such devices [2]. Using a FD-BPM model we investigate the performance to be expected from various flared laser structures in terms of both output power and beam quality. We clarify the influence of such material parameters as the number of quantum wells, the differential quantum efficiency and the linewidth enhancement factor on the output beam profile of the amplifier. We point out the influence of the linewidth enhancement factor showing that a reduction of this factor improves the output beam quality, the resistance to inhomogeneous injection, and the output farfield. Furthermore, a simulation of a 2D integrated elliptical lens is presented, showing the possibility of ‘on chip’ correction of the astigmatism for low α-factor structures. Such a lens would spare the use of an external cylindrical lens for collimation of the output signal.","PeriodicalId":365685,"journal":{"name":"Semiconductor Lasers Advanced Devices and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125533240","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}

This figure can be increased to about 50-60 mW by using some complicated fabrications techniques, but the goal of achieving higher powers and maintaining single mode operation has proved elusive. When the drive current to a single stripe laser is increased two effects may occur to limit the output power: the inversion population starts to saturate, and Catastrophic Optical Damage, (COD), starts to destroy the facets. Several approaches to these problems have been tried, eg., increased active area, and laser arrays, and have generally been found to be unsatisfactory. Increasing the active area does indeed result in increased output power but at the expense of the far-field pattern; and, unfortunately, increasing the active area generally leads to multi-mode operation, and hence a poor far-field.","PeriodicalId":365685,"journal":{"name":"Semiconductor Lasers Advanced Devices and Applications","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127070548","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}

Since the degradation of the output beam profile in a broad-stripe TWA is often observed in practice, two-dimensional models employing the beam propagation method (BPM) and the effective index method have been widely used [1-2]. These models are usually based on a linearization of basic material properties. For high-power TWAs, the operating current is several times larger than the threshold current of a corresponding laser diode. Linear approximations are under these conditions no longer valid. In this paper, we consider nonlinear material properties in a self-consistent BPM model. Nonlinear gain and residual facet reflectivities are found to greatly influence the operating characteristics of the devices.","PeriodicalId":365685,"journal":{"name":"Semiconductor Lasers Advanced Devices and Applications","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125692109","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}
