The absorption layer of the PD array in question includes the non-depleted, partially depleted, and depleted regions. This third-order composite absorber layer accelerates the diffusion of electrons in the absorber layer and balances the transport times of holes and electrons. Therefore, the high-speed and high responsivity characteristics of the device can be realized. The integration of InP microlenses on the backside of the PD allows the effective photosensitive surface area to be increased and the incident light alignment deviation to be compensated. Tests yielded a 3-dB bandwidth of the PD array at 1310 nm greater than 40 GHz, with a peak responsivity of 0.64 A/W.

Such operation drastically reduces onboard power consumption in large-area, pixelated arrays by driving only optically activated pixels. A modelling routine involving calculations of band structure, fraction of light absorbed, and responsivity have been used to analyse structures exhibiting an asymmetric quantum confined Stark effect. The proposed structure, compared with devices following similar modeling approaches, is predicted to exhibit an unbiased responsivity of 0.004 A/W enabling single pixel detection prior to triggering modulation. The calculated photocurrent of \u0000<inline-formula> <tex-math>$4~mu $ </tex-math></inline-formula>\u0000 A offers adequate signal to noise against dark current when operated in a photovoltaic mode. Furthermore, the strong blueshift in the ground state transition energy calculated for the applied field results in extinction ratios in excess of 4dB for the modulated signal.

The hybrid mode-locked (hybrid-ML) fiber laser integrates the nonlinear polarization rotation (NPR) technology with the CuO-ZnO-SA, producing remarkable characteristics with a central wavelength of 1045 nm, a 3-dB bandwidth spanning 18.26 nm, an ultra-short pulse width of 98 fs, a repetition frequency of 1.96 MHz, and an impressive signal-to-noise ratio of 51 dB. This research demonstrates a substantial enhancement in laser performance compared to NPR mode-locking alone. Notably, the pulse width experiences a significant compression, reduced by 39 fs, while the signal-to-noise ratio sees a noteworthy improvement of 11 dB. Furthermore, when contrasted with passively mode-locked pulse lasers relying solely on NPR technology, the hybrid passively mode-locked fiber laser attains a substantial reduction in output pulse width, surpassing 98 fs. These findings show the significant potential of the hybrid-ML system in the realm of ultrafast lasers, offering a promising avenue for future applications in cutting-edge research and technology.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140832560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatment consists of solving a coupled system of equations for the concentration of electrons in the active medium and those for the amplitudes of spectral components derived from Maxwell’s equations. Their numerical solution demonstrates the specific asymmetry of experimental laser spectra under microwave modulation of the injection current. The presented method also accounts for the simultaneous modulation at multiple frequencies. We demonstrate that the laser spectrum can be controlled to some extent, namely, its carrier can be suppressed and the ratio of the first sidebands powers can be simultaneously changed by additional modulation of the injection current at doubled frequency. In addition, we show that the phase difference of these components is stable under variations of modulation parameters in a relatively wide range.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139946262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
