Widely wavelength tunable semiconductor lasers are key components for
next-generation optical networks. Conventional tunable lasers require complex
fabrication processes such as non-uniform gratings and multiple epitaxial
growths, and need multiple electrodes with complex control algorithms for
wavelength tuning. As the dense wavelength division multiplexing (DWDM)
technology extends towards access and data center networks, the cost reduction
and operational simplicity have become more and more important.
Lightip has developed a simple and compact tunable laser based on patented
proprietary technologies. It consists of a half-wave coupled V-cavity laser with
only three electrodes: one for gain and direct modulation, one for channel
selection corresponding to the ITU grid, and the third for fine tuning when
needed. The laser structure does not involve any grating or epitaxial regrowth,
and has a size of only about 400mm
x 300mm.
The advantages of compactness, fabrication simplicity and easy wavelength
control offer cost-effective tunable laser solutions for many applications in
access and data center networks, and beyond.
The TLDXD series Transmitter Optical Sub-Assembly (TOSA) integrates a V-cavity
edge-emitting tunable laser, a power monitoring photodiode, an isolator, and a
TEC controller. The connector type can be chosen from LC, SC or fiber-pigtail
with FC/PC or FC/APC connector. It can provide up to 40 channels at 100GHz
spacing or 80 channels at 50GHz spacing in C- or L- band (other wavelength bands
available on request). The size of the 9-pin TOSA is only a small fraction of
that of the conventional butterfly package for tunable lasers.

Lightip has developed a simple and compact tunable laser based on patented

much smaller size compared to conventional tunable lasers. The advantages of
compactness, fabrication simplicity and easy wavelength control offer
cost-effective tunable laser solutions for many applications in metro/access
networks, datacenters and beyond.
The TLDXE series Transmitter Optical Sub-Assembly (TOSA) integrates a V-cavity
edge-emitting tunable EML laser, an isolator, and a TEC controller. The
connector type can be chosen from LC, SC or fiber-pigtail with FC/PC or FC/APC
connector. It can provide up to 40 channels at 100GHz spacing or 80 channels at
50GHz spacing in C- or L- band (other wavelength bands available on request).
Currently the tunable EML is available for 10Gbps and 25Gbps data rates.

The
tunable small form-factor pluggable (SFP) transceiver is based on
Lightip's patented proprietary technology, the half-wave coupled V-cavity laser
(VCL). The laser structure does not involve any grating or epitaxial regrowth,
and has only three electrodes for wavelength control, gain and direct
modulation, with a total size of only about 500mm
x 300mm. With the advantages
of compactness, fabrication simplicity and easy
wavelength control of VCL, this tunable transceiver offers a cost-effective
solution for tunable applications in access, mobile fronthaul and backhaul, data
center and metropolitan DWDM networks.
The TSFP15 Series single mode tunable SFP transceiver is hot-pluggable 20-pin
duplex SFP module compliant with SFF-8472 MSA. It is based on a Lightip's TLDX15
series tunable XMD TOSA, co-packaged with a PIN ROSA, and an SFP MSA compatible
interface. The optical interface is duplex LC connector. Currently it supports
2.5Gbps to 10 Gbps data rates with a typical fiber coupled output power of
3dBm, and can provide 16-32 channels at 100GHz spacing or 32-64 channels at
50GHz spacing in C- or L- band with a customer specified starting wavelength.
The transceiver module can be operated under ambient operating temperature
between 0 and 70℃. The size of the module is 69x13.7x13.3mm3.
