10 Gbps VCSELs with High Single Mode Output in 1310nm and 1550 nm Wavelength Bands

3-D Mesh-Based Optical Network-on-Chip for Multiprocessor System-on-Chip

“…The thermal related wavelength variations will result in additional optical power loss. Besides, VCSEL power efficiency degrades at high temperatures [29]. The work [12] systematically modeled and quantitatively analyzed the thermal effects in ONoCs.…”

“…Since they are surface emitting, high-volume production in arrays are possible. VCSELs operating up to 10-40 Gb/s have been reported in [29], [31], and [32]. This makes it possible to achieve high-speed optical transmissions.…”

“…For the evaluation of O/E conversions power consumption, we use the VCSEL model in [29], the serializer and deserializer designs in [38], and the VCSEL driver and TIA-LA circuit designs in [30]. Since the electronic part of the 3-D mesh-based ONoC is in 45 nm, we scale all the related power consumption linearly to 45 nm.…”

“…The thermal related wavelength variations will result in additional optical power loss. Besides, the VCSEL power efficiency degrades at high temperatures [29]. Based on the system-level analytical ONoC thermal model proposed in [12], we quantitatively study the thermal effects in the 3-D 8 × 8 × 2 mesh-based ONoC based on the low-cost optical routers.…”

Transverse-mode-selectable microlens vertical-cavity surface-emitting laser

“…The single-mode high-power microlens VCSEL may be an attractive source for optical interconnects with transmission distances in the order of 10-100 km [1], where the singlemode distributed feedback (DFB) laser is currently the solution. Firstly, single-mode highpower VCSELs consume 5 to 10 times less power than typical DFBs; small power consumption of a laser and its driver can be an important advantage for high-speed multichannel arrays.…”
