摘要	Nowadays，there is a growing interest in studying coupled cavity structures in vertical-cavity surface-emitting lasers（VCSEL）. These structures achieve a bandwidth enhance by adding a modulated current to the main cavity and a direct current to each feedback cavity. However，the impact on device performance when the main cavity is driven separately has not been thoroughly investigated. To gain a more comprehensive understanding of coupled cavity lasers，we designed and fabricated a square transverse-coupled-cavity VCSEL（TCC-VCSEL） with a side length of 30 μm×30 μm and investigated the variation of the device performance when the main cavity is driven separately. At room temperature，the -3 dB bandwidth was up to 30. 1 GHz，under non-return-to-zero（NRZ）modulation，clear eye diagrams were obtained at a back-to-back transmission rate of 40 Gbit/s，and relative intensity noise （RIN）was -160 dB/Hz. It has been proven that a feedback cavity can have a positive impact on the characteristics of the main cavity，even without driving conditions. The TCC-VCSEL device only requires one power supply，making it highly practical for high-density integration and providing new ideas for package integration applications. © 2024 Editorial Office of Chinese Optics.
