Large language models (LLMs) are rapidly advancing medical artificial intelligence, offering revolutionary changes in health care. These excel natural processing (NLP), enhancing clinical support, diagnosis, treatment, and research. Breakthroughs, like GPT-4 BERT (Bidirectional Encoder Representations from Transformer), demonstrate LLMs’ evolution through improved computing power data. However, their high hardware requirements being addressed technological advancements. LLMs unique...
We proposed and demonstrated a waveguide coupled fiber optic polymer micro-ring whispering-gallery mode (WGM) resonator side-coupled to bended nanoscale in D-shaped single (SMF). The flat region of the fabricated by femtosecond (fs) laser ablation was etched over core, which could be regarded as substrate with natural light input output ports, creating flexible platform for integrated photonics. were printed fs laser-induced two-photon polymerization (TPP) on “substrate”. design angled side...
A reconfigurable fully digital transmitter with carrier‐frequency (CF) pulse‐width modulation (PWM) is implemented in 180 nm CMOS for low CF applications. Through delay lines, baseband phases are mapped to position delays of 1/4 period a carrier clock. With lines based PWM, pre‐corrected envelopes converted pulse‐widths the position‐modulated Both and positions modulated clock amplified reshaped sine‐wave components by sequent switched‐mode power amplifier bandpass filter. The circuit‐level...
This paper describes a new design consideration for connectors of integrated optical strip wave-guides to single-mode fiber arrays in silicon V-grooves and some formulas determining position fibers dimensions are derived. The relationship between the coupling efficiency geometrical parameters waveguides this way also discussed. We can realize permanent connecting waveguides, simplify processes increase SM waveguides. As an example, (D equals 10 micrometer) waveguide (10 micrometer multiplied...
