HieFo has announced the launch of several new high-efficiency continuous wave (CW) distributed feedback (DFB) indium phosphide (InP) lasers, developed to meet the growing performance demands of siliconphotonics-based optical transceivers.
The company’s uncooled O-band CW laser series supports the CWDM4 wavelength plan across an extended operating range of -5 to 75°C while maintaining a minimum optical output power of 70 mW. These performance levels are enabled by a proprietary aluminum-free active quantum well design, offering a new benchmark in field-proven reliability and efficiency for non-hermetic, high-temperature optical transceiver applications.
In the area of coherent optical transmission, HieFo has further advanced the performance of its previously released HCL30 CW DFB laser chip. The latest version features a 1 mm cavity length and incorporates proprietary innovations covered by 12 newly filed patents. The device delivers typical optical output power exceeding 200 mW, sub-300 kHz spectral linewidth performance, and wall plug efficiency (WPE) greater than 30% across a broad output range. HieFo offers custom O-band wavelength variants of this design for coherent use cases in data center and PON architectures.
“HieFo’s latest product advances address the stringent performance standards required by the industry’s leading silicon photonic designs,” stated Harry Moore, HieFo’s Chairman & Co-founder. Mr. Harry added, that, “HieFo continues to execute on our core mission, which is to develop and produce the most efficient and reliable InP based chips in the industry.”
