The constant need for better light sensing technology is driving rapid advancements in wearable devices and smartphones. ActLight, a leader in semiconductor photonics, bridges the gap between cutting-edge research and real-world applications. We specialize in pushing the boundaries of light sensing technology. This article explores the technical advantages of ActLight’s technology and later discusses the benefits of our strong patent portfolio, which ensures secure integration for your next-generation devices.

A Growing Need for Advanced Light Sensors

The vital role of light sensors in consumer electronics cannot be overstated. Recent market forecasts by MarketsandMarkets predict a significant expansion in the global light sensor market, reaching an estimated value of $2.14 billion by 2025. This growth is fueled by the surging adoption of smartphones, wearables, and a plethora of smart devices. This trend reflects a fundamental shift in consumer behavior toward devices that offer enhanced functionality, advanced user interactions, and the ability to adapt to diverse environments.

Challenges and Breakthroughs: The Dynamic PhotoDetector (DPD)

Companies striving to meet this growing demand for feature-rich wearables and smartphones face several challenges related to integrating advanced light sensing capabilities. Traditional light sensors often struggle with limitations such as:

  • Suboptimal Sensitivity: Existing sensors can miss crucial light signals, hindering device performance and accuracy.
  • Excessive Power Consumption: High power requirements by traditional sensors drain battery life quickly, a major concern for wearable devices.
  • Cumbersome Form Factors: Bulky sensors limit design flexibility and can restrict device functionality.

ActLight’s Dynamic PhotoDetector (DPD) technology offers a revolutionary solution. The DPD represents a paradigm shift in light sensing, boasting unmatched performance in several key areas:

  • Unparalleled Sensitivity: The DPD exhibits exceptional sensitivity, capturing even the faintest light signals, ensuring precise data acquisition.
  • Low Voltage Operation: The DPD operates efficiently at low voltage, significantly reducing power consumption and extending battery life for wearable devices.
  • Compact Design: The unique design of the DPD makes it incredibly compact, allowing for greater design freedom and enabling the integration of light sensing capabilities into smaller, sleeker devices.
  • Cost-Effectiveness: ActLight prioritizes cost-effective production methods for the DPD, making this advanced technology accessible to a wider range of manufacturers.

CEO Serguei explains:

What we are doing, we are using devices slightly differently, in a dynamic way. Instead of keeping the voltage constant, we switch it from reverse to forward and detect the time when the forward current starts. Simply put, when everybody else would measure photocurrent, we are measuring time. The amplitude of the output signal is very high and can easily be measured without analog amplification, resulting in a significantly improved signal-to-noise performance compared to conventional photodiodes.
