Are you able to provide the insertion loss details for Perkinamine from any peer reviewed third-party published data (not cherrypicked by the company) or are you basing your investment decision solely on a slide deck from the company selling you shares to fund their paychecks.

Ok, let's play the AI game.

TFLN (Thin Film Lithium Niobate) modulators generally exhibit lower insertion losses compared to electro-optic polymer modulators. Here's a comparison of their insertion loss characteristics:

## TFLN Modulators

TFLN modulators are known for their low optical losses:

- The insertion loss for TFLN modulators, including coupling, can be as low as 3 dB[3].
- Some TFLN modulators have demonstrated insertion losses of only 1.5 dB[2].
- TFLN technology integrates well with low-loss SiN substrates, contributing to the overall low insertion loss[3].

## Electro-Optic Polymer Modulators

Electro-optic polymer modulators typically have higher insertion losses:

- Insertion losses for electro-optic polymer modulators are often in the range of 5-10 dB or higher.
- The higher losses are partly due to the material properties and fabrication challenges of polymer-based devices.

## Comparison

TFLN modulators offer several advantages over electro-optic polymer modulators in terms of insertion loss:

1. Lower overall losses: TFLN modulators consistently achieve lower insertion losses, often by several dB.

2. Better integration: TFLN can be integrated with low-loss waveguide materials like silicon nitride, further reducing overall system losses.

3. Stability: TFLN is more stable over time and temperature compared to polymer materials, which can degrade or change properties, potentially increasing losses over the device lifetime.

4. Scalability: The lower losses of TFLN make it more suitable for large-scale integration and complex photonic circuits where cumulative losses are a concern.

The superior insertion loss performance of TFLN modulators is one of the key reasons why this technology is gaining traction for next-generation telecommunication devices and integrated photonics applications[5].

TFLN (Thin Film Lithium Niobate) is generally considered a better option than electro-optic polymers when it comes to insertion loss for several reasons:

1. Lower overall insertion loss: TFLN modulators have demonstrated significantly lower insertion losses compared to electro-optic polymer modulators. TFLN modulators can achieve insertion losses as low as 3 dB or even 1.5 dB in some cases[1]. In contrast, electro-optic polymer modulators typically have insertion losses in the range of 5-10 dB or higher.

2. Material properties: TFLN is based on lithium niobate, which has excellent optical properties, including a wide transparency window (400-5000 nm) and strong electro-optic coefficients[3]. These properties contribute to lower optical losses and better overall performance.

3. Fabrication quality: TFLN can be fabricated using advanced techniques that result in high-quality waveguides with smooth sidewalls and precise dimensions. This level of fabrication quality helps to minimize scattering losses and other sources of insertion loss[1].

4. Integration capabilities: TFLN can be integrated with low-loss waveguide materials like silicon nitride, which further contributes to reducing overall system losses[2].

5. Stability and longevity: TFLN is more stable over time and temperature compared to polymer materials. Electro-optic polymers can degrade or change properties over time, potentially leading to increased losses throughout the device's lifetime[2].

6. Scalability: The lower losses of TFLN make it more suitable for large-scale integration and complex photonic circuits where cumulative losses are a significant concern[2].

7. Wide bandwidth: TFLN modulators can operate with extremely high bandwidth (approximately 250 Gbaud) while maintaining low insertion losses, which is crucial for high-speed optical communications[2].

These advantages make TFLN a more attractive option for next-generation telecommunication devices and integrated photonics applications where low insertion loss is critical for overall system performance.
