The expansion of cellular networks over the past decades has gone through an astonishing evolution. Due to centralized network functions, splitting of the generation/processing of RF signal in base band units (BBUs) and the baseband-RF conversion in remote radio heads (RRHs) has become inevitable. To systematically overcome the bandwidth and latency issues, a cost-efficient WDM-PON capable of linking...
We demonstrate direct modulation of a widely tunable microelectromechanical system (MEMS) vertical-cavity surface-emitting laser (VCSEL). The wavelength tuning is realized with electrothermal actuation of a SiO $_x$/SiN$_y$-based MEMS distributed Bragg reflector (DBR). The DBR is deposited in a low-temperature plasma-enhanced chemical vapor deposition chamber on a InP-based half-VCSEL by means of...
We report ultra-wide tuning of a 1550 nm BCB based high-speed MEMS-VCSEL. The MEMS is electrothermally actuated for a continuous tuning of 101 nm. Maximum output power and minimum threshold current is 3.2 mW and 2.6 mA, respectively.
We report 12 Gbps transmission over 6.3 km SMF with a directly modulated widely tunable bulk micromachined MEMS-VCSEL. The MEMS is electrothermally actuated for a continuous tuning of >64 nm around 1560 nm center wavelength. Error-free BTB transmission is achieved at 10 Gbps for 50 nm tuning.
We report direct modulation of a widely tunable surface micromachined MEMS VCSEL. The MEMS is electro-thermally actuated for tuning the emission wavelength over 60 nm with a center wavelength of 1554 nm. Error-free transmission is achieved at 10 Gbit/s for 47 nm tuning range.
