Abstract: Reconfigurable photonic devices are rapidly emerging as a cornerstone of next generation optical technologies, with wide ranging applications in quantum simulation, neuromorphic computing, and large-scale photonic processors. A central challenge in this field is identifying an optimal platform to enable compact, efficient, and scalable reconfigurability. Optical phase-change materials (PCMs) offer a compelling solution by enabling non-volatile, reversible tuning of optical properties, compatible with a wide range of device platforms and current CMOS technologies. In particular, antimony tri-selenide ($\text{Sb}_{2}\text{Se}_{3}$) stands out for its ultra low-loss characteristics at telecommunication wavelengths and its reversible switching. In this work, we present an experimental platform capable of encoding multi-port operations onto the transmission matrix of a compact multimode interferometer architecture on standard 220~nm silicon photonics using \textit{in-silico} designed digital patterns. The multi-port devices are clad with a thin film of $\text{Sb}_{2}\text{Se}_{3}$, which can be optically addressed using direct laser writing to provide local perturbations to the refractive index. A range of multi-port geometries from 2$\times$2 up to 5$\times$5 couplers are demonstrated, achieving simultaneous control of up to 25 matrix elements with programming accuracy of 90% relative to simulated patterns. Patterned devices remain stable with consistent optical performance across the C-band wavelengths. Our work establishes a pathway towards the development of large scale PCM-based reconfigurable multi-port devices which will allow implementing matrix operations on three orders of magnitude smaller areas than interferometer meshes.

@mapto@qoto.orgThis article suggests that research in 3D rendering contributed to machine- assisted assassinations of children in Gaza.
It is a topic very close to my heart. When I was starting my academic career at the dept. of Digital Storytelling of ZGDV in Darmstadt, Germany, I took a lot of inspiration by colleagues from the Institute of Creative Technologies at the University of Southern California. Their work was funded by DARPA and a lot of it was about military training. Let alone the fact t…

@chris@mstdn.chrisalemany.caThere were actually a lot of good recommendations from that Committee report, the one on PR was just the final one! Here's a few more.. including some that local #Fediverse proponents could dig into! @… was on the Committee.
—>FEDI ADVANTAGE<— “The Committee heard about a number of issues related to
the electoral information environment. Members recommend
that the provincial government collaborate with Elections
BC and the federal government to review existing legislative
and regulatory measures related to misinformation,
disinformation, and hate speech during elections, including
**mechanisms to ensure the timely removal of harmful content** (**emphasis added)”
—> FEDI ADVANTAGE<— “To better address challenges associated with social media and emergent technologies such as artificial intelligence, Members recommend establishing a working group to propose amendments to BC’s privacy and election legislation. To better protect all users, the Committee recommends requiring digital platforms to act with a duty of care and establish clear safety-related requirements such as data privacy, platform design, and content policy. The Committee also heard about concerns regarding foreign interference, and recommends that these be considered by the Electoral Integrity Working Group.”
—The Committee heard about the critical importance of
civic education to ensure the public’s understanding of
democratic institutions, processes, and participation. The
Committee recommends strengthening civic education
in the K-12 school system with input from experts and a
greater emphasis on applied learning.
— the Committee suggests enhancing data collection by requiring proactive enumeration on an annual basis and ensuring that registered parties and candidates can access poll-by-poll results. Elections BC should review and improve
voter registration practices and communication, as well as
access to and public awareness of voting opportunities. With respect to expanding voter eligibility, the Committee supports further examination of extending voting rights to 16- and 17-year-olds as well as permanent residents in BC.
— Committee Members recommend modernizing the candidate nominator verification process, requiring Elections BC to collect and share voters’ contact information with registered political parties and candidates, and strengthening measures related to access to multi-unit buildings for candidates and their campaigns.
