Wavelength Locking and Determination in Tunable Lasers by Gain Voltage Measur…
In this paper we demonstrate the feasibility of low-cost lasers with an integrated wavelength locker and wavelength meter. We use a reflection at the polymer chip to single mode fiber butt coupling…
Influence of Losses on the Laser Voltage Drop of the Active Section
We present a model of a tunable distributed Bragg reflector (DBR) laser describing the effect of cavity losses on the gain voltage. Theoretical and experimental results are in good agreement. Measu…
Second Harmonic Generation in Polymer Photonic Integrated Circuits
Second harmonic generation is an efficient way to create coherent radiation at wavelengths that are not accessible with standard laser sources. In this work we demonstrate second harmonic generatio…
Effect of Optical Feedback on the Wavelength Tuning in DBR Lasers
Optical feedback has an impact on the tunability of lasers. We created a model of a tunable distributed Bragg reflector (DBR) laser describing the effect of optical feedback from a constant reflect…
Influence of Integrated Optical Feedback on Tunable Lasers
In this paper we explain how to use rate equations to describe a laser that includes integrated optical feedback. We find a relation between the threshold current, the voltage drop at the gain sect…
