Highly reliable and high yield 1300 nm InGaAlAs directly modulated ridge Fabry-Perot lasers, operating at 10 Gb/s, up to 110/spl deg/C, with constant current swing

Abstract

Transceivers for 300 m multimode links, based on a serial 10 Gb laser source and incorporating receiver based Electronic Dispersion Compensation, EDC, are creating the first high volume application for 10 Gb FP (Fabry Perot). A highly reliable and high yield uncooled ridge Fp laser i s presented. The device shows excellent power characteristics in the 25-150 "C temperature range with very high TO (95 K in the temperature range 0-85 "C and still 78 K at 1.50 "C). Outstanding dynamic performances are also shown. 6dB of extinction ratio can be achieved up to 110 "C, by using a constant current swing of 50 mA OCIS codes: (140 5960) semiconductor laser

Parametric study of 1310 nm ridge waveguide AlGaInAs‐InP semi‐conductor laser dynamics

“…FP lasers are less expensive to fabricate than other existing solutions such as the distributed feedback (DFB) laser and the laser integrated electro‐absorption modulator. AlGaInAs lasers have been shown to be reliable at high temperatures [2] and capable to operate within the wavelength specification (1310 nm) required for GPON upstream transmission.…”
