The VCSEL, which has a wavelength of 1539.84 nm, has been characterized both statically and dynamically. The sensitivity of a single photodiode heterodyne receiver using the proposed 2.5 Gb/s VCSEL transmitter is -39.5 dBm. Thus, this transmitter is an extremely cost-effective solution for future access networks.2017http://zaguan.unizar.es/record/16783710.1364/OL.42.000583http://zaguan.unizar.es/record/167837oai:zaguan.unizar.es:167837info:eu-repo/grantAgreement/ES/MICINN/TEC2014-59583-C2-1-Rinfo:eu-repo/grantAgreement/ES/MINECO/TEC2013-46917-C2-2-Rinfo:eu-repo/grantAgreement/ES/UZ/CUD2013-05Optics Letters 42, 3 (2017), 583-586All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
