A Circuit-Based Scalable and Low-Complex Optical Datacenter Network

The ever‐increasing bandwidth requirements of modern datacenters have led researchers to propose networks based upon optical circuit switches, but these proposals face significant deployment challenges. In particular, previous proposals dynamically configure circuit switches in response to changes in workload, requiring network‐wide demand estimation, centralized circuit assignment, and tight time synchronization between various network elements— resulting in a complex and unwieldy control plane. Moreover, limitations in the technologies underlying the individual circuit switches restrict both the rate at which they can be reconfigured and the scale of the network that can be constructed; a new approach is necessary.

Air-Cavity Dominant Vertical Cavity Surface Emitting Lasers

Vertical-cavity surface-emitting lasers (VCSELs) have many applications, including potential use in optical coherence tomography (OCT) and optical fiber communications.  Both fields are rapidly growing and there is a need for widely-tunable VCSELs than can be used as the wavelength-swept sources in OCT.  One technique that could increase the tuning range of a VCSEL would be to use an engineered semiconductor-air- coupling (SAC) interface.  However, a concern is that engineering the SAC region in a tunable VCSEL would cause the laser threshold to sharply increase.  Therefore, researchers have not pursued that approach.  Instead, researchers have applied an anti-reflection (AR) layer at the semiconductor-air interface or modified the layer orders in the top distributed Bragg reflector (DBR) to extend the tuning range.  However, the AR layer has to be one quarter-lambda thick with refractive index close to the square root of the product of the semiconductor refractive index and the refractive index of air. Researchers have developed a novel layer structure for vertical-cavity surface-emitting lasers (VCSELs) which further enable its use for widely wavelength-swept coherent light sources and multiple-wavelength VCSEL arrays. This design has recently led to a record-breaking tuning range for electrically-pumped VCSELs.

Two-Dimensional Patterning Of Integrated Circuit Layer By Tilted Ion Implantation

The proliferation of information technology (IT) – which has had dramatic economic and social impact – has been enabled by the steady advancement of integrated circuit (IC) technology following Moore’s Law, which states that the number of transistors on an IC “chip” doubles every two years. In other words, the primary reason for increasing the number of components (transistors) on a chip is to lower the manufacturing cost per component. Increased integration also has the benefits of providing for improved system performance and energy efficiency. Therefore, the semiconductor industry has steadily scaled linear transistor dimensions, by a factor of approximately 0.7´ with every new generation of manufacturing technology, over the past 50 years. The most advanced chips today comprise over 10 billion transistors within an area of a few cm2. The pace of IC technology advancement has slowed down for the most recent generations, however, due to fundamental limits of the conventional photolithographic patterning process. Double-patterning techniques such as “self-aligned double patterning (SADP)” are used today to pattern IC layers with sub-45 nm feature size and minimum pitch, well below the wavelength of light used in the photolithography process. These techniques involve many additional steps, including extra lithography and etching processes, however, which result in increased cost of patterning.  To address the issue of increasing patterning cost, researchers at the University of California, Berkeley have developed a new method for patterning an IC layer with minimum feature pitch smaller than the minimum pitch of the photolithographic process and with minimum feature size smaller than the lithographic resolution limit, using well-established planar processing techniques.  A significant advantage of this new method is that it can be used to define two-dimensional layout patterns, which can provide for more compact integrated circuits.

Interposers Made From Nanoporous Anodic Films
